Chapter 14, Problem 20P

For the following pairs of voltages and currents, indicate whether the element involved is a capacitor, an inductor, or a resistor, and find the value of C, L, or R sufficient data are given:

a.	$v=550\sin (377t+{50}^{\circ })$
	$i=11\sin (377t-{40}^{\circ })$
b.	$v=36\sin (754t+{80}^{\circ })$
	$i=4\sin (754t-{170}^{\circ })$
c.	$v=10.5\sin (wt-{13}^{\circ })$
	$i=1.5\sin (wt-{13}^{\circ })$
