An LED indicator lamp in a circuit is switched on.
A charge of 5.4 C passes through the lamp in a time of 12 s.
Calculate the current in the circuit.
Use the equation:
current=chargetime \text{current} = \frac{\text{charge}}{\text{time}} current=timecharge32 exam-style questions on Edexcel GCSE Physics 10.1 Circuits, charge and current. Each one has a worked solution and a mark scheme showing where the marks go.
