10.4 STEP RESPONSE OF AN RL CIRCUIT BY SOLVING DIFFERENTIAL EQUATION
is the solution for the current in the RLcircuit with unit step voltage input and zero initial
condition. Notice that the expression evaluated at t 0
+
turns out to be 0 as it should. We will
have a lot to say about exponential functions in the context of RL circuits in the remainder
of this chapter. However, we will get to that after we solve the RL circuit step response prob-
lem by solving the governing differential equation in time-domain in the next sub-section.
