Just one! You'd never believe it but you only need one wire in a curcuit. unless things are stopping it then you need more. it depends on what materials you are using. my physics teacher always told me that the clips on the end of the wire are crocodiles and if i didnt do my experiments properly, i would be eaten alive :) i was the best student in the class after that experience.

How many wires does a straight 220V circuit have?
A straight 220V circuit utilizes two wires per circuit.
How many wires must a current have?
Current needs only one wire to flow in, but a circuit needs at least two wires to connect the source to the load.
What happens if you move a switch and the circuit wires are not all connected?
When a switch is open (wires not connected) it is considered off. When a switch is closed it is considered on. If you move a switch and the wires are not connected the the circuit is open and current cannot run throughout the circuit to power the device.
In a shorted circuit what happens to the temperature of the wires?
In a shorted circuit, the temperature of the wires increases. This is because the wires are not perfect conductors - they have resistance - so the large fault current that flows generates a voltage across the wires, which then generates power, generating heat.
How many wires can you connect to a circuit breaker terminal?
The code says one wire per one terminal.
How many wires does a straight 220V circuit have?
A straight 220V circuit utilizes two wires per circuit.
How many wires have electric circuit?
It depends! IDIOT
A three phrase circuit has how many hot wires?
Three wires carry the three phase energy.
How many neutral wires are needed for lighting and outlets?
If they are on the same circuit you only need 1 neutral wire in the circuit.
What do long straight lines represent in a circuit diagram?
They are the wires through which current flows when the circuit is closed.
What does neutral do?
Neutral wires are actually ground wires. They enable the circuit to be completed.
A break in the wires of an electric current will the circuit and the current?
A break in the wires of an electric current will break or cut the circuit and stop the current from flowing.
What do you mean by a complete closed circuit?
A circuit without any nonconducting wires
Why are circuit made of meatal?
well ummm...... the circuit has metal in it to carry on the wires!
How many wires must a current have?
Current needs only one wire to flow in, but a circuit needs at least two wires to connect the source to the load.
What are the conductors in a circuit?
The wires carrying the power.
What happens if you move a switch and the circuit wires are not all connected?
When a switch is open (wires not connected) it is considered off. When a switch is closed it is considered on. If you move a switch and the wires are not connected the the circuit is open and current cannot run throughout the circuit to power the device.
