What is the current in a circuit if the charge passing each point is 20C in 40s? Answer:

Given,

Charge moved, Q = 20C Time taken, t = 40s

To find, Current, I = ? We know that, I = Q/t

Substituting the values in the above equation we get I = 20/40 = 0.5A

Therefore, 0.5A is required for moving 20C charge in 40s.
