Chapter 14, Problem 18P

The current through a 2 k $\Omega$ capacitive reactance is given. Write the sinusoidal expression for the voltage. Sketch the u and i sinusoidal waveforms on the same set of axes.

$\begin{array}{l}\text{a}\text{. }i=50\times {10}^{-3}\text{sin} wt\hfill \\ \text{b}\text{. }i=2\times {10}^{-6}\text{sin}\left(wt+{60}^{\circ }\right)\hfill \end{array}$
