Current, voltage, and what they measure
Understand that electric current is the rate of flow of charge (measured in amperes using an ammeter), and that potential difference (voltage) is the energy transferred per unit charge (measured in volts using a voltmeter)
Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
If your child sets up a circuit with an ammeter and a voltmeter, can they explain what each one is measuring and describe the difference between current and voltage?

Check understanding
- States that current is measured in amperes (A) and is the rate at which charge flows around a circuit
- States that potential difference (voltage) is measured in volts (V) and represents energy transferred per unit charge
- Correctly connects an ammeter in series and a voltmeter in parallel when building or interpreting a circuit
