Answer 1

A coil of copper wire is connected in series with a bulb,a battery and a switch because copper is a good conductor of electricity.

Explanation:

• Most of the electrical appliances use copper wire.
• This is because copper is a good conductor of electricity. Therefore less amount of current is required for the appliances to work.
• Usually a battery and a bulb and switch are connected in series so that the bulb can be switched off when required.
• Copper allows the free flow of electrons in the direction opposite to that of flow of current. This is responsible for the flow of current through the copper coil.
