How many wires in a circuit?

Answer 1

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.

Answer 2

A circuit typically consists of two wires: one for the flow of electrical current from the energy source (usually the positive terminal of a battery) and one for the return path of the current back to the energy source (usually the negative terminal of a battery).

Answer 3

Basically two, the live and the return (neutral). It's good also to have an earth (ground) for safety.

Answer 4

0? Bit of a philosophical point. With 1 you have a simple but rather boring series circuit.

Answer 5

Circuitry wire size is based on the amount of amps that the circuit is to draw. The higher the amperage the larger the wire size has to be.
