Question

The current passing through a terminal is given by i = 4t3 − 3t2. How much charge entered the terminal between t=1 s and t=3 s. A. 54 C B. 20 C C. 100 D. 80 C

Answer 1

54

Step-by-step explanation:

The derivative of charge with respect to time equals to the current. Therefore if we take the integral between t=1s and t=3s, we would get the charge entered the terminal.
