A series RL circuit in a power amplifier with resistance R = 500 and inductance L = 10H has a
constant voltage V = 100V applied at t = 0 by closing a switch.
Given:
E
R
switch

L
Voltage Drop across Resistor (VR) is IR,
Voltage drop across the Inductor (VL) is directly proportional to the rate of change of
current passing through the inductor,
