A 0.160 H inductor in series with a 85.0 ohm resistor and an ac source. The voltage across the inductor is
vL = -(11.0V)sin[(473 rad/s)t]
a. derive an expression for the voltage vr across the resistor. express your answer in terms of the variables L , R , vL (amplitude of the voltage across the inductor), ω , and t.
b. What is vR at 2.04 ms?
