400
Name at least 3 types of energy that can be produced in a circuit.
Heat, light, sound, mechanical, elecrical
500
Explain what a conductor does.
A conductor allows energy to flow through easily.
500
Why are wires insulated with rubber?
The rubber is an insulator and keeps the electricity on a straight path and it keeps us safe from the electric current.
