The current in an LED indicator light remains constant at 0.18 A.
Calculate the charge flow through the LED in 55 s.
Use the equation:
charge flow=current×time \text{charge flow} = \text{current} \times \text{time} charge flow=current×time Q=I×t Q = I \times t Q=I×t32 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.
