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×tPractise Edexcel GCSE Physics Charge, current and potential difference with exam-style questions for Foundation and Higher tier. 50 questions, matched to the Edexcel GCSE Physics (1PH0) specification and written in Paper 1 and Paper 2 style.
