On the specification
| Board | Spec | Statement |
|---|---|---|
| AQA GCSE 8463 | 4.2.4.1 | Power |
| Edexcel GCSE 1PH0 | 10.30 | Explain how the power transfer in any circuit device is related to the potential difference across it and the current in it |
| Edexcel GCSE 1PH0 | 10.31 | Recall 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 J249 | P3.2l | Explain 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 J249 | PM3.2ii | Recall and apply: energy transferred (J) = charge (C) × potential difference (V) |
| OCR GCSE J249 | PM3.2iii | Recall and apply: power (W) = potential difference (V) × current (A) recall and apply: power (W) = (current (A)) |
| OCR GCSE J249 | PM3.2iv | Recall and apply: energy transferred (J, kW h) = power (W, kW) × time (s, h) |
For teachers
