Question

explain why conductors and insulators are both required to construct the electrical wiring in your home

Answer 1

Conductors are required to transmit electricity to various parts of the home. These take the form of the copper in the wires. Insulators separate various electrical conduits from each other and external bodies, as well as protecting the conductors from the elements. These take the form of the plastic sheathing over the wires. 

Answer 2

As conductors let electrons pass through them easily, when there is a current, the conductor lets the electrons pass thru them giving the person a shock. This is why we need insulators. But having only insulators are also a problem as the insulator won't let electrons pass thru them not giving out electricity in your house
