6.1 The RL Circuit cont.
Switching Operations cont.
For t > 0 the switch is closed and the circuit is the same as before
So the DC steady-state solution is the same as before, and as a result of the inductor’s current continuity (see text p. 119), i(0+) = i(0- ) = 0 A. (same as before) so the solution is the same as before except i(t) = 0, t < 0 (assuming the switch was open for all t < 0)¾see below
