Your pool pump should be on a GFCI breaker if it was properly wired. What you have is a current leakage problem possibly due to moisture leakage getting into the windings of the motor. Rectify this problem before using the pool. If you don't have GFCI breakers protecting the pool pump and normal...
If there's a broken wire then the circuit is no longer closed. It'sopen.
Three things that are needed to have an operating electricalcircuit are: 1. Electric potential difference or voltage. 2. Conductive path, which allows the movement of charges such aswire. 3. Resistor, which acts as an electrical resistance and looselydefines any object that uses electricity to do...
The three types are Line to ground faults line to line fault double line to ground fault three phase line to ground fault
a device which output voltage is almost the real peak valueof an applied signal
by dividing the peak voltage by the square root of 2, or about1.414.
Bcoz the emf which is to be measured is less than emf of driving cell....
Constantan is a metal alloy made of 45 percent Nickel and 55 percent Copper. Constantan wire is used chiefly in electrical instruments and and other equipment which can take advantage of its unusual physical property which is that, even over wide variations in operating temperature, its...
Start with the load of 0.2 watts. The power rule says that watts equals volts times amps, or amps equals watts divided by volts, so 0.2 watts at 120 volts means 0.00167 amps. Now, look at Kirchoff's current law, which implies that the current in a series circuit is the same at all points. This...

the thing that transmits electricity like cooper is a conductor
Answer . The room fuse in my '99 626 protects _ignition-off_ function of the power door locks, headlights, and some other functions, IIRC including all operation of the radio. For example, if the Room fuse is blown, my power locks work, but only with the ignition switch on.\n. \n. \nDoc.
It creates an iron bar with wire coiled around it. It can also create a spring, provided it stays in the same place for long enough so that it holds it's shape.
Silver is a better heat conductor.
The actual act, meaning how bad the person was hurt. Then there isintent, or weather the perpetrator was trying to hurt the victim.If it is done with intent to kill or with a dangerous weapon it isaggravated battery, and the sentence can be greater.
Your question is too broad. Here's my answer. WIRES.
Dont know!!!!!!! ask the teacher and by the way, what is ammeter?
V=IR, if V is constant the relationship between I and R is hyperbolic.
Resistance start-induction run motors are commonly known as split phase. They are only single phase motors. They have 2 sets of windings, the Start winding which is high resistance and low inductance made for thin wire, and the Run winding which is low resistance and high inductance made for thick...
twice the frequency that is rectified.
Principle of Working: A Moving Coil Galvanometer works on the Electromagnetic effect of current carrying coil (free to move) being placed in an air-gap between the soft iron core and the strong pole pieces of the magnet. The current following in the moving coil which is the specimen to...
An electrical motor is such an electromechanical device whichconverts electrical energy into a mechanical energy. In case ofthree phase AC operation, most widely used motor is Three phase induction motor as this type of motor does notrequire any starting device or we can say they are self...
The Ohm is the name of the unit used to measure resistance . R esistance is the name given to something which opposes the flow of an electrical current in a circuit.
Though it is not possible to get a mathematically perfect square wave from a sine wave, it is possible to get a reasonably close square wave from a sine wave. A clipper circuit is one which clips off the top of a sine wave thus giving it a flat top. Clipper circuits find their applications in...
Applications of Voltage shunt feedback amplifier?
I assume you are asking how much energy a 5-hp motor will consume in one hour? The first thing to understand that a motor is rated according its output power which, in North America, is expressed in horsepower and, elsewhere, in watts. So, the output power of your motor is 5 hp, which is...
Yes, they are not switches and not made to cycle daily. A few times does not hurt them.
The symbol " I " was used by André-Marie Ampère, after whom the unit of electric current is named and stands for " intensité de courant": Current Intensity.
The r.m.s. value of an alternating current or voltage is the value of direct current or voltage which produces the same heating effect.
Running current. The locked rotor amps are only seen at initialstart up which only lasts a fraction of a second to one or twoseconds.
Because it's hard, and inductors take up a lot of space, and usually whatever purpose the inductor is being used for can be accomplished by some other combination of electrical components that are more easily fit onto an IC.
They are used to decouple a circuit. Basically you divide the circuit in two but they share the signal that is coupled in the transformer without physically connecting the two circuits. This gives you dc blocking, great interference blocking, but at the same time you have the same signal on both...
Basically an analog circuit is any circuit which uses the voltage (or current) level to deliver information (say.. a sine wave or an audio output). In contrast a digital circuit would only use a high and a low voltages (square wave, binary data transfer etc). Discrete circuits are circuits only...
Generally an ohmmeter will be more accurate near the middle to upper range or the selected range - this is because it will be rated at an error of a certain ohm + / - a certain percentage. As you increase, the base ohms stays the same, but becomes a smaller percentage.
Of course. Additional resistors change total resistance, which changes current, which affects power.
I would say that probably the fuse holder is loose, this would cause a voltage drop and result in heating of the fuse. Replace the fuse holder.
Generators transform energy into electrical energy. The output of the generator is the electric power it "makes". The input is whatever is used to create mechanical energy to turn the "prime mover", or the thing that makes the generator spin (be it steam / thermal energy, water, wind, etc.).
The ASTM tests soap, cars and so many more of everyday objects andsometimes none everyday objects.
Unless the motor is used for SPA/pool type use, it does not need a GFCI. Motors can cause nusiance GFCI trips due to sparking at start up. Ideally motors should be operated on dedicated circuits.
Measures current by magnetic field induced into the clamp. You need to clamp a single conductor. For example you couldn't just clamp a lamp cord since it has two conductors and the current is going in opposite directions and the fields cancel each other out.
because it can magnetize and demagnetize easily
The flow of electric charges is current .
You have to follow the lines. Could be blown fuse or any number ofother things. Follow it back to the service.
LED bulbs com in different powers, so there's no way to tell. At a guess a 10W LED might compare to a 60W incandescent.
Radio may be a suggests that of communication employed by Transformers and humans. A transmitter may be a part of electrical device anatomy permitting them to speak victimisation radio, instead of sound.
Converter is a software that convert formats such as convert avi to mp4. There are many DVD converter and video coonverter in the market.
They're not. They're usually copper or aluminium, which are metal !
ATX computer power supplies provide low volts DC of less than five volts. AT computer power supplies provide low DC only to five and twelve volts.
grace ann gonzaga want's to know about generation of computer?
A switch is a device that stops and starts current flow in a circuit.
Answer . 22 x 277 x 3 or 1.73 x 480 x 22. or more accurately:. 22 x 277.1283 x 3 = 18.29 kW. or. 1.7320508 x 480 x 22 = 18.29 kW. ----------------------------------------------------------------------------. Theory:. S = V a I a * = |V a | | I a | = {|V ab | / }| I a | = S. Thus, S 3 = 3 S = 3 {...
advantages . used for long distance communication . high speed data transmission . many reciver stations can receive signal from the same sender station disadvantages . very costly
Because of resistance we lose a lot energy in the form of heat. Getting rid of resistance can sometimes save a lot of resources, as well as decrease operating temperatures of electric equipment. However it must always be remembered that cooling conductors to a low enough temperature to make them ...
Multiple by 100 - 4.5 X 100 = 4500mA
Basically, the light from the bulbs are lost at about the same time.
More than 11KV over head conductor called as High Tension .... Another Answer 'High tension' is an archaic term for 'high voltage'.
Two phase is not used anywhere. What you may be thinking is centertapped single phase (negative voltage at one terminal, neutral at0, and positive at the other, all in phase so you can get 120 voltsor 240 volts). Open delta would be used for three phase power. Asingle transformer can be used for...
They both measure the amperes in a circuit. If you go to the store and ask for an ammeter you will get a meter that with the right circuitry attached will measure amps. That little meter on the front of a battery charger is an ammeter. If you purchase a piece of equipment that measures the...
You don't. You need to get a new one.
The electrical current needs to flow. It comes it through the hotand out through the neutral.
Generators can be required to generate real and reactive power. When operating in a leading mode, the generator is generating real and leading reactive power (inductive power). This means the generator is "sucking in VARS", which will pull down the terminal voltage similar to an inductor. It can...
Types of DC Motors •DC motor • Permanent Magnet DC Motor • Separately Excited DC Motor • Self Excited DC Motor • Shunt Wound DC Motor • Series Wound DC Motor • Compound Wound DC Motor • Cumulative compound DC motor • Short shunt DC Motor • Long...
A grounded neutral will be at earth potential. A floating neutral will be at a voltage dependent upon the voltage imbalance between phases, and the design of the transformer.
We used to use a thermocouple embedded in the wall of the mixer (shaped flush) on both Banbury and extruders. You could also use a digital pyrometer to look at the surface temperature.
INDUCTIVE RESISTOR: Any circuit in which change in current is accompained by change in flux and therefore by inuced emf is said to be inductive. NON-INDUCTIVE: if a double wire is wound arround an insulating rod,the emf can not be induced because the wire is doubled back on itself at its centre...
The biggest problem is that one or both of you will get tired and/or frustrated. All you can do to resolve this problem is remember why you are working out this relationship or remind your partner why you two decided to try and work on the relationship in the first place. Remind each other how much...
There is no simple, straight forward, one-fits-all formula. There is a method, however-creating a thevanin equivalent circuit with one resistive element and your voltage source, you can convert this to a current source (I = V / R).
The total resistance of the circuit increases. hence the new resistance after adding the resistance will be new resistance = old resistance + added Resistance There is a small mistake in the question. The second word is 'changes' not 'charges'
Richard Trevithick in 1804.
It has been calculated that one big cheer from the spectators in a football stadium has enough energy to boil a cup of water. Now, although heating water takes quite a bit of energy, this actually isn't very much from so many people.. A microphone works by sound vibrations moving a coil past a...
With Daubechies you can use practical subband coding scheme. You don't have to no the actual wavelet and scaling functions, but rather you need to know low-pass and high-pass filters related to a certain Daubechies wavelet family.
The only place the magnets on a maglev train could be to perform their designed function would be on the very bottom, spread in a line running fore to aft. A second bank of magnets would be in place of the typical rail lines underneath the train, with similar poles of the two groups of magnets...
A load not connected to ground but connected in a feedback circuit is floating load
This depends on the application. It may be OK to do so, or it may result in problems. If this is an already designed circuit, and you have a 820u cap that has blown, I suggest replacing with a 1000u (in my experience, this is more common and readily available), AND i usually up the voltage rating on...
The term electricity is a general one, and it can be applied to any moving charges. But in the world of today, we generally think of electricity as the movement of electrons, those little particles that carry the negative electrostatic force. We usually think of electricity as a flow or movement...
High resistivity is the inverse of conductivity, and Carbon is not a good conductor (although it could be a better conductor than most hydrocarbons). Here are a few examples: Carbon - 0.07 x 10 6 S cm -1 (not a good conductor) Silicon - 1.2 x 10 -5 S cm -1 (not a good conductor - used for this...
If the OLTC is on the secondary, and the secondary voltage is high, the OLTC will tap down, which will lower the voltage. Typical range of OLTC is +/- 10%. The primary may also have multiple taps so the OLTC can be set at '0' under normal conditions.
Unbalanced load can cause inefficiencies with three phase transformers (you cannot use full nameplate capacity of the transformer), and severe unbalance can cause protective equipment to operate (zero sequence/ground and negative sequence), enough unbalance can cause difficulties with three phase...
traffic signal,blind person,
Nothing. That's why it's a parallel circuit. If it was a series circuit, then the first bulb would go out.
