Question:
At time t=0, an initially unenergized 10-H inductor is connected to a 12-V battery for two seconds, then short-circuited. What is the current in the inductor \(-\infty<t<\infty \)
Below is the work I have done so far and I'm not sure if it is correct.
I assume the method to use is for inductors
For the two seconds when it is connected to the battery, i have determined the current follows
\(V=L {di\over dt}
V=12
i=\int {V \over L} dt
i(t)={12 \over 10} t
\)
But this doesn't seem right because it's unreasonable that the current is unbounded and can just increase indefinitely.
I haven't a clue what the current in the inductor is like when it is short-circuited.
