sufficient set of data needed to solve for the inductor current in an RL circuit from that time
instant onwards.
10.2 SERIES RLCIRCUIT WITH UNIT STEP INPUT – QUALITATIVE ANALYSIS
In this section, we study the behaviour of inductor current in a series RL circuit excited by
a unit step voltage source qualitatively. The initial current in the inductor at t 0

is
assumed to be zero for the purpose of this analysis.
Unit step voltage is defined in the following manner. It has a step discontinuity at
t 0, and strictly speaking, the time instant t 0 is excluded from the ...
