Chapter 1, Problem 1.25P

The current and voltage of an electrical device are $i_{ab}\left(t\right)=5\text{A}$ and $v_{ab}\left(t\right)=10\sin \left(200\pi t\right)\text{V}$ in which the angle is in radians.

1. Find the power delivered to the device and sketch it to scale versus time.

Determine the energy delivered to the device for the interval from t = 0 to t = 5 ms.

Repeat for the interval from t = 0 to t = 10 ms.
