As a connector to connect all parts of a circuit.

12.

Why must parts of a circuit be properly connected before the bulb can light up?

a)

To ensure that the bulb can light up.

b)

To ensure that the battery can produce light in a closed circuit.

c)

To ensure that electric current can flow through the closed circuit.

13.

Look at the diagram. Why did the bulb not light up?

a)

The bulb was fused.

b)

The battery had not enough electric current to light up the bulb.

c)

The switch was opened and prevented electric current from flowing through the circuit.

14.

The diagram shows a complete circuit but the bulb did not light up. Why?

a)

The plastic spoon is an insulator of electricity and prevented electric current from flowing through the circuit.

b)

The plastic spoon is not connected properly and prevented electric current from flowing through the circuit.

c)

The plastic spoon is a conductor of electricity and prevented electric current from flowing through the circuit.
