(Part 1: Video Activity)

Lets check if our basics are clear 😇

Multiple Choice

When does an electric shock happen?

• it occurs when someone scares you

• it occurs when someone touches live or damaged wires, causing current to flow through the body

• it occurs when someone touches live or damaged wires, causing resistance to flow through the body

Multiple Choice

What is a short circuit?

• it is when a wire overheats due to very low voltage in a wire

• its when a circuit is cut short into smaller segments

• it is when a wire overheats due to very low resistance in a wire

Multiple Select

• Circuit Breakers

• Ammeter

• Fuse

• Voltmeter

• Earth wire
