Questions 13-relate to the circuit shown below in which the switch has been open a long time so that the current I is 10 mA. v 1 ΚΩ 4 mH W W + 3 ΚΩ w m 4 ΚΩ 4 ΚΩ w T 20 2004 F 18. The energy stored in the field of the inductor (before the switch is closed) is most nearly (A) 0.2 m (B) 0.2 m) (C) 0.4 m) (D) 0.02 J Questions 8-9 refer to conditions immediately after the switch is closed. 20. The current lis most nearly equal to 19. Compared to conditions just before the switch was closed, the energy stored in the capacitor is (A) 0 (B) Sma 10 mA D) 20 mA (A) double (B) the same (C) one-half (D) zero
