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

• The bulb was fused.

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

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

Look at the circuits in the diagram. In which circuit will the bulb be brighter?

• Circuit A

• Circuit B

• Both circuits, the bulbs will have the same brightness.

Look at the circuits in the diagram. In which circuit will the bulb be brighter?

• Circuit C

• Circuit D

• Both circuits, the bulbs will have the same brightness.

State one advantage of bulbs arranged in parallel arrangement in a circuit.

• When one bulb fused the other can still light up.

• Reduce the amount of electric current used for both bulbs.

• Both bulbs in a parallel arrangement in circuit will share the electric current produced by the battery.

What type of circuit is this?

• Parallel Circuit

• Open Circuit

• Series Circuit
