For the RL circuit, find the inductor current before t=0, after t=0 & long after t=0, equivalent R, time constant and an expression for the inductor current
For the RL circuit, the switch has been closed for a long time before it opens at time t=0
a) Find the inductor current right before t=0
- b) inductor-current right after t=0
- c) inductor-current a long time after the switch is open
d) Find the equivalent resistance that the inductor sees after the switch opens?
e) Find the time constant for t>0
f) Find an expression for the indicator current i(t) for t>0
d. attempt to find the owner, then leave your information if you cannot find them.
d. represents both (b) and (c).
more logical as well.
b and c are to complicated.
glad i could , give me a follow, so if you need with any other question, im here.
the answer is d
