• 
• 
• 

Which requirements an electric circuit needs to work?

• Batteries connected form positive to negative, a closed loop and a battery.

• A switch and a motor.

• A battery.

In a series circuit potential is divided into the different components of the circuit.

• True

• False

In a paralel circuit if one component is not working the rest will work.

• True

• False

Materials such as iron, clips and aluminium paper are....

• insulators

• conductors

In this circuit, if we switch on the switch the non-broken bulb will work.

• It will work because the potential is divided

• It won't work because it's a series circuit and the potential is not divided.

• repel

• atract
