The switch S is closed at t = 0. Which statements about the following RL circuit are true? (Assume a DC source and that the inductors have no resistance.) Circle all answers that apply. L L R (A) Immediately after the switch is closed, the source sees an equivalent resistance of R/2. (B) Immediately after the switch is closed, the source sees an equivalent resistance of 2R. (C) Immediately after the switch is closed, the source sees an equivalent resistance of 3R/2. (D) At t = infinity after the switch is closed, the source sees an equivalent resistance of R. (E) At t = infinity after the switch is closed, the source sees an equivalent resistance of 2R. (F) At t = infinity after the switch is closed, the source sees an equivalent resistance of 3R/2.
