Why is a battery important in an electrical circuit?
As a source of energy.
As a path for electricity to flow through.
As a connector to connect all parts of a circuit.
Why must parts of a circuit be properly connected before the bulb can light up?
To ensure that the bulb can light up.
To ensure that the battery can produce light in a closed circuit.
To ensure that electric current can flow through the closed circuit.
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.
The diagram shows a complete circuit but the bulb did not light up. Why?
The plastic spoon is an insulator of electricity and prevented electric current from flowing through the circuit.
The plastic spoon is not connected properly and prevented electric current from flowing through the circuit.
The plastic spoon is a conductor of electricity and prevented electric current from flowing through the circuit.
Why electrical wiring usually are covered with a layer of plastic?
To make it look pretty
To help electricity flow along the wire
