Prof said one thing, book says another. R/L source-free circuit, pic included :)
Hello everyone. This time after reviewing my professors work, and comparing it to the books solution manual i bought, they don't seem to match. The way the professor explained it to me made me think she was right. She said since it wants u to find Isw @ 5x10^-6 seconds, the current is diminshed enough that u can say its gone. Since IL and Isw are in opposite directions, Isw is just -IL. But the book said f that.
Here is my work and the problems directions:
After being in the configuration shown for hours, the switch in the circuit is closed at t = 0. At t = 5micro seconds, calcualte (a) IL and (b) Isw
