A current of 4A flows around a circuit for 10s. How much charge flows past a point in the circuit in this time?

Given, Current, I = 4A

Time taken, t = 10s To find,

Charge moved, Q = ? We know that,

I = Q/t

Substituting the values in the above equation, we get 4 = Q/10

Q = 4×10 = 40C

Therefore, 40C charge is moved in 10s when the current flowing is 4A.
