If everything is connected and working correctly, there shouldn't be (probably). The purpose of a switch is to interrupt current. -Is this new? Has it been wired correctly? Are you sure? -How are you measuring this? Is the amount of current flowing within the error margin of your measuring...
Battery, bulb, switch and conductors that connect everything together.
This is relatively easy if you are careful. However, you could kill yourself if you are not careful. Safety gear such as insulated rubber gloves, eye protection and rubber sole shoes all provide a margin of safety. Also have someone standing by to drag you away from a live circuit if you happen to...
An ammeter either directly, or via a current transformer, is used to measure current in a circuit. Current transformers (CTs) are necessary when either (1) you need to measure the large currents flowing in high-voltage systems (a CT will isolate the HV system from the ammeter to which it is...
Current in a series circuit is a flow of charges that is equal at any point in the circuit.
Torque is the cross product of radius and force .Torque is a twisting effect..
Torque is the cross product of radius and force .Torque is a twisting effect.
A purely resistive load is one in which there is no capacitive or inductive reactance. Whe driven by an AC voltage source, such a load will have no shift in phase angle between voltage and current.
Yes there is single phase for 600 volts. It is used for lighting.You need a transformer which gives you 600 volts plus a neutral.The voltage for the one phase to neutral is 347.
Its 0.7 times peak-0 voltage, 106 mv RMS.
Current = charge / time = 10 / 5 = 2 amperes
False, new motherboards often include a 4 or 8 pin cable to provide power exclusively for the processor.
Yes it depends on many variables such as what the wire is made of the size of the wire whether the wire is a multi strand wire. What governs the amount of voltage a wire can carry is the insulation that is wrapped around the wire. Like wire with ratings of 300 volts, 600 volts and 1000 volts...
its an amotor can work at both dc or ac supplies
The terms "conduct" or "conduction" describe the transmission of heat and electricity.
These terms apply to the coils inside a wattmeter . 'Pressure coil' is an archaic term for 'voltage coil', which is connected in parallel with the supply, while the 'current coil' is connected in series with the load.
A ground fault circuit interrupter is the device used to de-energize the circuit.
Yes, the plow is an additional draw that the truck didn't have before. You may need to put a heavier alternator on or hook it up to a battery charger when not using it.
The effective resistance of the combination is the reciprocal of [ (1/20) + (1/60) + (1/40) ]. (1/20) + (1/60) + (1/40) = (6/120) + (2/120) + (3/120) = (11/120) The effective resistance is (120/11) = 10.91 ohms (rounded) It makes no difference what the resistors are connected across, or...
parallel operation of generators is nothing but giving the same source of energy to the two or more units.
it makes a rainbow!!!!!!!!!!!!!!!! :D
these instruments operate on the interaction between two magnet field.the signal current to be measured routed through a fine wire coil suspended in the field of permanent magnet.the coil wound round an aluminium frame which is a cylendrical soft iron core.a spiral spring connected to the pointer...
I hear you saying that "joule" should be a unit of "ability"; that's pretty slippery. "Joule" is a unit of energy. The capacitor does store energy. The energy stored in a capacitor is [ 1/2 C V 2 ], measured in joules. ' C ' is the capacitance, in farads. ' V ' is the voltage across the...
A parallel circuit is used when the current through several components needs to be independent of each other. The simplest example is that of lights in a home. The lights with their switches are wired in parallel. Turning on one light does not affect any others and similarly, turning a light off...
An open (circuit) is where insufficient (often zero) current flow where some is expected. In this case, little or no work is done. A short (circuit) is where high (often infinite or as limited by the power supply) current flows where only some is expected. In this case also, little or no work is...
A coil of wire is an inductor. It's power factor should be very near zero. It will not be zero, since the wire has real resistance as well as inductance.
This depends on the source. If you're using a function generator, it will be whatever the function generator is rated for. For AC power transmission, some countries operate at 50Hz, and some at 60Hz. The actual range that is allowable may be 1-2 Hz above or below the generally operated frequency....
1. You must size the conductors at 125% of the motor FLC 2. You must size the overloads from 115% to 125% of the motor nameplate current rating
in series with other elements
It depends on where the resistor is added. If it is placed across the load, the current increases. If it is placed in series with the load the current is reduced.
Consider it a kiosk as such. You will not be able to be "kicked out to the web", it is like a website without outside links. You can interact with the iPad through touch, but all links remain with the site.
Find capacitance: C = Er * Eo * A / d C = (1.0005898) * (8.854Ã10 â12 )* (1meter squared) / 2 x 10^-6 C = 4.42 micro farads To determine charge Q: Q = C*V = 4.42 x 10^-6 * 10 volts = 4.42 x 10^-5 coulumbs.
Run another wire from the electrical panel.
All other gates can be made from NAND or NOR gates.
kW = (V Ã I Ã PF Ã 1.732) Ã· 1,000. now if we assume unity PF and solve this equation for "I," we get: I = 1,000kW Ã· 1.732V.

It makes and breaks four separate contacts. Think of a switch forexample that connects one wire to one wire. A 4 pole contactor islike 4 separate switches going on together.
This is a number that indicates what range the transmitter willwork correctly. This will depend on how strong the transmitter is.
Electrical engineering would include such things as transformers and switchgear, conductors, motors and generators; and almost always concerned with the energy component of electrical systems. House and automobile wiring and systems including lighting would also be included. Electronic...
yes, you can. in A/C motor rps(rev/sec) is N(rps)= f/p where f is the frequency and p is the number of pair poles. By increasing or decreasing the frequency the rps will change accordingly. By having less or more pair poles the rps will be increased or reduced. the more pair poles the lower will be...
If there are 4 ammeters in a parallel ciruit and one reads 0.8, the readings of the rest are indeterminate, because it depends on the individual branch resistance. !st answer, again, but better worded . . . Assuming that the 4 ammeters are in parallel with each other, and otherwise in a series...
V=I*R Resistance = Voltage / Current
Yes, an electric current is the flow of charged particles.
Could be a floating ground. Measure between "earth" and Hot. For earth find a copper pipe that is grounded to earth or a cast iron drain pipe.
A5uf capacitor has 5*10-4 coulombs of charge stored on its plates
40 A -providing the voltage remains constant.
The surge protector would let the surge go through to destroy thecomputer. With very hgh resistance, vey little current would flow.
If you add a resistance in parallel with any one or more resistors in the circuit the total resistance will decrease. If you put it in series with any resistor the total increases.

For resistors in a series (connected end to end), the resistances simply add together. If the resistors are in parallel (side by side), things are a bit more complex: take the inverse of each resistance ( 1 / resistance ), and add them together; then take the inverse of the result. This looks...
A kilowatt equals 1000 watts. watts=volts x amps.
The "full load speed" is the speed at which a motor has been designed to turn - usually measured in RPM (revolutions per minute) - when it is delivering its full rated output power.
the unit of "e.m.f" is "volt"
There are several types. One sort uses a special transistor known as a 'Hall effect' transistor. The gain of these transistors alter when the magnetic field around them changes. This needn't be a magnet, but merely magnetic material, such as steel. There is an amplifier and switching circuit built...
An electromagnetic field.
This depends on voltage and temp rating of the line (at a minimum, there may be other factors such as needing to get over a road, river, etc., topography of the land...). There is a minimum height lines (the actual wire, not the pole necessarily) must maintain - for 12.5kV, they should not dip below...
Resonance at sub synchronous speeds or frequencies. Generators designed to run at 60 Hz may have a sub synchronous resonance at 20 Hz, for example. If run at a resonant frequency, the resonance can cause increasing vibrations that will eventually do very bad things (things will start to break).
As with all things, temperature does change things. With amplifiers, the changing temperature in the power transistors running the speakers can become a ruining experience. The louder you play, the more heat is generated in these transistors. The hotter they get, the less current do they stand....
A voltage can be induced on a ground wire by other wires nearby. If you have more than one ground wire, The induced voltage will cause a current flow up one, and down through the other. By removing one of the two, you interrupt the loop.
Hard to define... A four year old child has the strength to physically "make" a typical household circuit breaker, while a teen would be able to "make" a typical industrial circuit breaker. (The latter breaker being physically much larger than the former.).
Circuit breakers have their "breaking...
Silicone (a semiconductor) is used in IC's because it is plentiful, and can be fairly easily dopped with P and N type materials to create transistors and diodes. The semiconductor is used as a base to build off of.
Fully loaded - 2.62 amps at 11kV. The no load depends on the transformer design, but it will usually be significantly less than the full load amps (not sure on this size, but on larger transformers it is typically ~.05 - .1% full load, so you'd be looking at ~2.5 mA RMS). The connection type is not...
For an ideal switch, there will be no voltage drop across it. In reality, there will be a very small voltage drop, and this will be dependent on how well made the switch is, and what it is made out of.
pl all my friend explain icu and ics of mccb as there is so many confussion
Ok so if you have to take the 5 amperes and multuply them by the 22 ohm resistance giving you the answer of 110 5 * 22 = 110 volts
rc coupling is a coupling that involves capacitor aand resistor
It's an electrical generator converting mechanical power intoelectrical power. The electrical power comes out in the form ofsingle-phase alternating current.
"Current" cannot be stored at all in any way; when you stop it moving, it isn't current any more and moving it means using it. The energy carried however, can be stored in several different ways.
More electrons means more current, by definition.
Ohm's Law Voltage = Current x Resistance
Best way is to use a clamp on amp meter. You need to be able to put the clamp over a single conductor. This is usually easy to do in the electric panel, but for a device you need to split the conductors. You can take an extension cord you don't need and separate the conductors so you can get the...
Actually Inductor oppose the change of current in the circuit..... Acts like a short circuit in steady state condition....
What is the current running through the entire circuit? 3 amps In a series circuit the current is the same in each resistor. The voltage across each resistor will be the current multiplied by the resistance.
An induction motor cannot run at synchronous speed because it is the "slippage" of the rotor relative to the rotaing magnetic field that generates the current in the windings contained within the rotor. This induced (hence the term induction) current sets up the opposing magnetic fields that cause...

Conversion of electrical energy into mechanical energy
negative ground systems have always been in use but some chose to use positive grounds as wires were poorly insulated and suffered from corrosion on negative earth systems but positive earth systems did not suffer as badly to corrosion (i heard somewhere Henry ford came up with the positive ground...
Voltage is stepped up to higher voltages for transmission in a power transmission system in order to reduce the current required to deliver a certain power and, as a result, to reduce the size of the conductors required. Remember that power is current times voltage, so increasing the voltage allows...
For a transformer 50 degree c is stable. In most transformers if temp rises above 60 an alaram will sound ,if above 90 trip off. a temp controller which will measure the oil temp will do this actions.
