Outcomes
- Pupils can
- Use of P = IV, higher currents leads to hotter wires
- Ammeter in series, voltmeter in parallel
Specification References
2.4 know some of the different ways in which electrical heating is used in a variety of domestic contexts
2.5 understand that a current in a resistor results in the electrical transfer of energy and an increase in temperature
2.6 recall and use the relationship, power = current x voltage, P=IV and apply the relationship to the selection of appropriate fuses
2.7 use the relationship between energy transferred, current, voltage and time: energy transferred = current x voltage x time, E = ItV
2.8 recall that mains electricity is alternating
