I have a question about the following homework problem.
The charge enters the positive terminal of an ekement is given by q(t) = -12e^-2t mC. The power delivered to the element is p(t) = 2.4e^3t W. Computer current in the element the voltage across the element and energy delivered to the element in the time 0 < t < 100ms
I know that current is equal to the derivative of charge
i = dq(t) / dt
But when I take the derivative of q(t) i get 24e^-2t which does not give me a constant. Do I plug in 100 ms into 24e^-2t and subtract that from 24e^-2t evaluated at 0?
Thanks for any help!
