cant learn every individual move of the system but i know what the  fuel cell will be good for
  == Answer ==     2 wire has a live wire to energise the field where as the single wire alternator self energises and does not need the powered feed.
There are four basic factors of inductor construction  determining the amount of inductance created. These factors all  dictate inductance by affecting how much magnetic field flux will  develop for a given amount of magnetic field force (current through  the inductor's wire coil):   1....
The progression from Shockley diode to SCR is achieved with one  small addition, actually nothing more than a third wire connection  to the existing PNPN structure. If an SCR's gate is left  floating (disconnected), it behaves exactly as a Shockley  diode. It may be latched by breakover voltage...
An electrician works on small-scale repairs while an electricalengineer design, test, and oversee the manufacture of electricalequipment. Another Answer An electrician is a tradesman who has undergone a recognisedapprenticeship, and is responsible for installing and repairingelectrical...
in transformer oil use for isolation   Answer    An 'isolation transformer' is a transformer specifically  used to electrically-isolate the secondary circuit from the primary  circuit. Of course, ALL mutual transformers do this, but an  isolation transformer normally has a 1:1 ratio,...
A rather strange question, as most transformers are installed by trained individuals who wouldn't be using this forum for help. However, it will be necessary to refer to the manufacturer's specifications for that specific transformer in order to determine how to achieve the desired output.
A three-phase separator is used in the oil industry to separate  oil, water and gas from a mixture.
Any write has resistance and electrical energy is converted to heat  and magnetism over any distance, but when the distance gets very  long this energy loss becomes significant.I actually think that AC  looses less energy than does DC, which is why they use AC in the  power grid, why I don't...
you would wire a float switch into the control circuit i.e, the  contactor coil (which is relatively low current but rated at least  for the control voltage,, in most cases 120VAC). also in the same  circuit would be the overload contacts. if the overload trips  and/or the float switch opens...

you would need a motor starter/contactor with the contactor coil  rated at your control voltage. the motor is wired through the  contactor main contacts and the control circuit wired into the  contact coil
float switches are not rated for motor currents, therefore you  would need a motor starter/contactor to handle to motor current and  the float switch would be wired into the coil circuit, i.e.,  control voltage source.. I'm guessing 120VAC wired through the  float switch to the contactor coil...
Not much, yet. Homopolar motors work on a principle called the Lorentz force law, the same principle that makes a rail gun work. They are the most basic and conceptually simple rotary electric motors possible. You may also see them referred to as Faraday Disks, or unipolar motors. Because they are...
n India the demand of electricity per head is more than generation  of electricity.    Moreover till December 2011, over 300 million Indian citizens had  no access to electricity. With the growing population the demand  also increasing. However, generation of electricity is not  increasing...
Current cannot pass through a dieletric material in a capacitor. In  fact charge is induced at the second plate. In steady state no dc  can flow. In transient terms a current flows but it doesn't pass  through the capacitor itself, charge mearly builds up at the second  plate. With ac this is...

In a distribution transformer's star-connected secondary, the common point of connection is called the 'star point' and is connected to earth. The star point then provides the neutral connection for the transformer secondary, providing a return path for any unbalanced currents due to an unbalanced...
The primary winding of a transformer is connected to the supply, while the secondary winding is connected to the load.
It is used for slicing foods with less physical effort and it makes  neater slices. The knife part is two serrated blades that are  clipped together.

A switch opens or closes an electrical circuit. A limit switch is a switch that is arranged to open or close an electrical circuit when a physical parameter is at its limit. Often, the limit is physical travel, such as a limit switch that prevents an electro-mechanical device from operating beyond...
DYn 11 is a Delta HV winding and star lv with theneutral brought out. At primary substations it is usual to have a neutral ct. The ct is a last line of defence operating a standby earth fault relay which opens the lv circuit breaker (11kV). It may have a stage 2 setting in case the lv breaker fails...
It works normally. Well actually there are 380 volts across two  lines of a 3 phase AC source, so it should work normally.

An open loop system is simple and straightforward, requiring fewer  physical or logical connections as the closed loop design. It lacks  the feedback offered by closed loop designs. As such, it is often  considered inferior to a closed loop design.   A closed loop design assures the initiator...
There should be an LA, LB, LC, and N. LA is a single phase live  connection (of 3)
If there's a broken wire then the circuit is no longer closed. It's  open.
Three things that are needed to have an operating electrical  circuit are:   1. Electric potential difference or voltage.   2. Conductive path, which allows the movement of charges such as  wire.   3. Resistor, which acts as an electrical resistance and loosely  defines any object that...
  The three types are Line to ground faults line to line fault double line to ground fault three phase line to ground fault

 == 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.    ...
The actual act, meaning how bad the person was hurt. Then there is  intent, or weather the perpetrator was trying to hurt the victim.  If it is done with intent to kill or with a dangerous weapon it is  aggravated 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?
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...

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. Resistance 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...
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 equivalent...
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 initial  start up which only lasts a fraction of a second to one or two  seconds.
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...
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.
The ASTM tests soap, cars and so many more of everyday objects and  sometimes 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.
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 of  other things. Follow it back to the service.
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.

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 current...
The electrical current needs to flow. It comes it through the hot  and out through the neutral.
