Any circuit has at least two conductors. Otherwise, by Kirchoff's current law, there would be no current, therefore no power, therefore no work. The current coming on one wire is exactly balanced by the current going out on the other wire. If there is a third wire/connection, such as a ground wire, it is possible for current to flow on that conductor as well but, usually, there is no current expected to flow on the (safety) ground conductor.
What else can I help you with?
Does the current in home wires oscillate due to oscillating ac voltage in homes?
Yes. In almost all cases, the current follows the voltage waveform. The peak amplitude of the current depends on the device or appliance that's drawing the current.
Why are circuit made of meatal?
well ummm...... the circuit has metal in it to carry on the wires!
Why do you hear strange sound beneath high tension wires?
the current causes alternating magnetic fields which shake the wires and they get warm so snow and rain sizzle off the wires.
What can connect all the components in a circuit so that an electric current can flow?
Wires
Why you use only single phase and three phase supply?
Single phase requires 2 wires - a hot, and a return (both wires of the same size. Three phase requires three (same size), and if it is grounded will require a forth (doesn't normally carry current so it can be small). Two phase requires three wires (two phase conductors of one size, and a return that can handle double the current of the phase conductors), or four wires (same size for all, effectively two separate single phase supplies). It isn't economical is the bottom line. It costs ~the same (in wire) for two phase as three, and you get 50% more power delivering capability with three phase.
Do neutral wires carry current in an electrical circuit?
No, neutral wires do not carry current in an electrical circuit. They are used to complete the circuit and provide a return path for the current to flow back to the source.
What is a neutral wires' function?
To carry the unbalanced load current.
What are the differences between white, green, and black wires in electrical wiring?
White wires are typically neutral wires that carry current back to the power source, green wires are ground wires that provide a safe path for electricity to flow in case of a fault, and black wires are hot wires that carry the current from the power source to the electrical device.
What are the differences between black, hot, white, and neutral wires in electrical wiring systems?
Black wires are typically used as hot wires to carry electrical current, while white wires are used as neutral wires to complete the circuit. Hot wires carry the current from the power source to the electrical device, while neutral wires provide a return path for the current to flow back to the power source.
What is the difference between white and black wires in electrical circuits?
The difference between white and black wires in electrical circuits is that white wires are typically used as neutral wires, while black wires are usually used as hot wires. Neutral wires carry current back to the power source, while hot wires carry current from the power source to the device being powered.
Why do different wires have different thicknesses?
Different wires have different thicknesses to accommodate various levels of electrical current. Thicker wires have lower electrical resistance and can carry more current without overheating. Thinner wires are suitable for lower current applications and are more flexible and easier to work with.
Why are wires supplying electric current to the water heater thicker than those supplying current to the lights?
the water heater operates at high power compared to the lights and so the water heater requires a larger current. The wires supplying current to the water heater are thicker so that the wires have a low resistance. This reduces the risk of the wires overheating.
What wires carry current?
A wire with some resistance and a voltage applied to it The amount of current I passing this wire is V/R
What are all of the names of the appliance wires?
The names of common appliance wires include live, neutral, and ground wires. Live wires carry electrical current, neutral wires complete the circuit by returning current to the source, and ground wires provide a path for electricity to safely discharge in case of a fault.
What is overload current?
A current greater than which a circuit is designed to carry , may melt wires or damage elements of the circuit.This is known as overloading of current.
What are the differences between white and black wires in electrical wiring?
White wires are typically used as neutral wires in electrical wiring, while black wires are commonly used as hot wires. Neutral wires carry current back to the power source, while hot wires carry current from the power source to the electrical device. It is important to follow proper wiring codes and guidelines to ensure safety and efficiency in electrical systems.
How many number 10 wires can fit in a 1 EMT conduit?
16 current carry conductors
