Web21 dec. 2012 · 2) Its asks for the rate of change of current at t=0. I am aware that there is no current through the inductor at t=0 due to the inductor opposing the current change (back emf etc) but there IS a current rate of change at t=0 and it can be calculated as: initial di/dt = E/L Amps. If I use this I get 50A/s as an initial current rate of change. Web3.8K views 2 years ago. The switch in figure is closed at time `t = 0`.

Web4 dec. 2024 · EDIT: After some reading, I think your supposed to treat the circuit as a DC circuit at t=0. Then I (S) = 0 A. an inductor would act as a short. a capacitor would act as open. If the circuit above has an inductor then I (L) = 0 A. If the circuit above has a capacitor instead of inductor then I (C) = 0 A. Share.
