Question

Calculate the current that flows through a circuit when 50 coulombs passes down a wire in 20 seconds. use the equation: charge flow = current × time (q = i t) show your working out and state the unit.

Answer 1

To find the current, divide the charge flow (50 coulombs) by the time (20 seconds), which yields a current of 2.5 amperes.

Step-by-step explanation:

Calculating Electric Current

To calculate the current that flows through a circuit when 50 coulombs of charge pass down a wire in 20 seconds, we can use the equation charge flow = current × time (q = i × t). We are given the charge flow (q) which is 50 coulombs and the time (t) which is 20 seconds. Using these values, the calculation for current (i) is as follows:

Current (i) = Charge Flow (q) / Time (t)

i = 50 C / 20 s = 2.5 A

The unit for measuring electric current is the ampere, abbreviated as A, so the answer is 2.5 amperes.
