Chapter 1, Problem 11P

The charge entering the positive terminal of an element is given by the expression $q\left(t\right)=-12e^{-2t}\text{ mC}\text{.}$ The power delivered to the element is $p\left(t\right)=2.4e^{-3t}\text{ W}\text{.}$ Compute the current in the element, the voltage across the element, and the energy delivered to the element in the time interval $0<t<\text{100 ms}\text{.}$
