1. The problem statement, all variables and given/known data Find instantaneous value UL after commutation. 2. Relevant equations type of commutation - switch key(I hope I've translated it correct) Use operator method and classic method 3. The attempt at a solution K1=1.2 K2=0.7 K3=1 J=8*K1 L=10*K1 R1=K2*8 R2=K2*8 R3=4*K3 R4=12*K3 I need to find UL in the moment of commutation?
