@HughHuang96824 Yeah for FR2 the last few things I got counter-clockwise, and I did do what you did to find the current :).

BTW: for the first frq, form M b, ii, you got I=.12e^-TR/L, and I’m not sure if I did too I don’t really remember what I got for the coefficient. But for the exponent, -TR/L, couldn’t you substitute in the R and L values since they were given? R was 200 ohms and L was like 0.5 Henries I believe. Lol I remember the only variable I had in my exponent was T for time, but idk I might have gotten it wrong but idk it’s a silly small error, probably would’ve gotten -1 or something for that.
