What is an electric circuit?

• The path which the electric current takes.

• The movement or flow of negatively charged electrons

• The presence of electrons

• An electric charge that collects or builds up on the surface of an object

In series circuit, there is only _____ path for electrons to flow.

• One

• Two

• Three

• Four

In series circuit, the lights are connected ________ to each other.

• Side by side

• Parallel

• Close by

• Effectively

If one of the light bulb in series circuit is taken off, what will happen to the other light bulb?

• The other light bulb will be on

• The other light bulb will be off

• The other light bulb will stay on

• Both light bulb will be on

In parallel circuit, there are _________ pathways for charge to flow.

• One

• Two or more

• None

• Zero

In a parallel circuit, if we remove one of the light bulb, what will happen to the other light bulb?

• The other light bulb will stay on.

• The other light bulb will be off

• Both light bulb will be on

• Both light bulb will be off

If we add more light bulbs into a parallel circuit, how will the brightness of the bulbs change?

• It will get dimmer

• It will get brighter

• The brightness will stay the same

• None of the light bulb will be on

Which one is the circuit diagram of this picture?

What is the advantage of having a safety switch or fuse in the electric circuits of your house?

• Safety switches break the circuit when there is no fault

• Safety switches switch the electrical current

• It prevents the circuit from overheating and starting the fire

• Fuses are fused together with electrical wires
