Electric Circuits

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.

What makes up an electric 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.

What is a conductor?

•  A material that allows electricity to flow through it.  The circuit is complete. 
• A material that does not allow electricity to flow through.  It stops the flow of electricity.
• A light switch.
