(a) Name the material used for making the connection wires. Give reason for your answer. (b) Why should a connection wire be thick?

(a) Copper or aluminium are the materials utilised to make connection wires because they have a low specific resistance and hence have low resistance in their wires.

(b) The connecting wires are thick enough that their resistance to the flow of electricity via the circuit is considered insignificant.
