What analogy is used to explain the concept of amperes?

• Brightness of a light bulb

• Speed of a car

• Amount of water flowing through a pipe

• Flow of air in a balloon

What happens if a circuit is not complete?

• No current flows

• Current still flows

• Current becomes unstable

• Current doubles

What does a switch do in an electric circuit?

• Decreases resistance

• Increases current flow

• Changes the voltage

• Completes or breaks the circuit

What is the function of a fuse in a circuit?

• To convert AC to DC

• To increase current flow

• To prevent excessive current flow

• To decrease electron flow

What happens when a fuse is rated for a lower amperage than the current flowing through it?

• The fuse increases resistance

• The fuse opens the circuit

• The fuse has no effect

• The fuse enhances the current

Which current direction is used in conventional current?

• Negative to positive

• Random direction

• Positive to negative

• Circular motion

What was the historical mistake made regarding the direction of current flow?

• Believing it didn't flow

• Assuming it flowed from negative to positive

• Assuming it flowed from positive to negative

• Thinking electrons didn't move
