Exercise 29

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