1. The problem statement, all variables and given/known data The current in a wire varies with time according to the equation I(t) = 6.00 A + (4.80 A/s)t, where t is in seconds. How many coulombs of charge pass a cross section of the wire in the time period between t = 0.00 s and 3.00 s 2. Relevant equations I=dq/dt 3. The attempt at a solution So since were calculating the current, i solved for q=(integral)I*dt which was the integral from 0 to 3 (6.00A+(4.80)t and got the answer q = 75.6 which is wrong. The answer is q= 39.6. I know the problem lies in the math but im not sure where im wrong.
