Inductors & DC Transients (Mixed)

In a circuit inductance LL and capacitance CC are connected as shown in figure. A1A_1 and A2A_2 are ammeters. When key KK is pressed to complete the circuit, then just after closing key (K)(K), the reading of current will be

Figure

Show answer and solution

Answer: (d)

  1. Just after closing, an uncharged capacitor acts like a short circuit, so the CC-R1R_1 branch carries its maximum current V/R1V/R_1.
  2. An inductor opposes any sudden change, so the current in the LL-R2R_2 branch is zero at that instant.
  3. So the answer is (d) maximum in A1A_1 and zero in A2A_2.
