On the specification

BoardSpecStatement
AQA GCSE 84634.2.4.1Power
Edexcel GCSE 1PH010.30Explain how the power transfer in any circuit device is related to the potential difference across it and the current in it
Edexcel GCSE 1PH010.31Recall and use the equations: electrical power (watt, W) = current (ampere, A) × potential difference (volt, V) electrical power (watt, W) = current squared (ampere2, A2) × resistance (ohm, Ω)
OCR GCSE J249P3.2lExplain how the power transfer in any circuit device is related to the potential difference across it and the current, and to the energy changes over a given time
OCR GCSE J249PM3.2iiRecall and apply: energy transferred (J) = charge (C) × potential difference (V)
OCR GCSE J249PM3.2iiiRecall and apply: power (W) = potential difference (V) × current (A) recall and apply: power (W) = (current (A))
OCR GCSE J249PM3.2ivRecall and apply: energy transferred (J, kW h) = power (W, kW) × time (s, h)
For teachers

This GCSE Physics lesson teaches electrical power: P = VI and P = I² R. It suits Foundation and Higher tier students.
