If 30C of charge is flowing through a circuit in 2 minutes, what is the current?

0.25A

Explanation:

Given parameters:

Quantity of charge  = 30C

Time taken  = 2minutes  = 2 x 60 = 120seconds

Unknown:

Current through the circuit = ?

Solution:

To find the current through the circuit, use the expression below;

      I  =

Q is the quantity of charge

t is the time taken

 Now, insert the parameters and solve;

         I  =   = 0.25A
