What electricity and circuits means

You learn how electric current moves in a circuit and why a closed path is needed. You also see which materials let current pass through easily, so you can understand simple wiring and everyday electrical devices.

What you will practise

  • Identify when a circuit is complete or broken.
  • Choose materials that conduct electricity well.
  • State the unit used for electric current.
  • Link wires, switches and current in simple circuits.

Before you start

You should already know that electricity can flow through some materials and not through others. It also helps to know basic circuit parts such as a battery, wire and bulb.

Worked example

One question from this skill's own question bank, shown with its full working.

Question

What is needed for a circuit to work?

  • A gap in the wire
  • A complete loop
  • Two batteries only
  • A switch turned off
Answer: A complete loop

Working: Current only flows when the circuit is a complete, unbroken loop.

Common mistakes to avoid

  • Thinking current can flow through a broken circuit. Check for a complete loop before giving an answer.
  • Choosing any metal as a conductor without checking. Remember that copper is a very good conductor.
  • Using volts instead of amperes for current. Match the unit to what is being measured.
  • Confusing the path of current with the switch position. A switch must allow a closed path for flow.
