A fault in a household appliance caused a person to receive an electric shock before an electrical safety device tripped. The mean power transferred to the person during the shock was 1.8 W1.8\text{ W}1.8 W. The potential difference across the person was 120 V120\text{ V}120 V. Calculate the electrical resistance of the person.
Practise AQA GCSE Physics Current, potential difference and resistance with exam-style questions for Foundation and Higher tier. 82 questions covering Standard circuit diagram symbols, Electrical charge and current, Current, resistance and potential difference, and Resistors, matched to the AQA GCSE Physics (8463) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
