Question 11

An LED indicator in a circuit has a current of 0.8 A passing through it.

Calculate the quantity of charge that flows through the LED in 45 s.

State the unit of charge with your answer.

Use the equation:

charge flow=current×time \text{charge flow} = \text{current} \times \text{time} charge flow=current×time
