In the circuit shown, the capacitor is initially charged with a 12V battery, when switch `S_(1)` is open and switch `S_(2)` is closed. `S_(1)` is then closed and, at the same time, `S_(2)` is opened. The maximum value of current in the circuit is A. `0.38` mAB. `0.84` mAC. `0.72` mAD. `0.1` mA |

Answer» Correct Answer - C `1/2Li^(2)=1/2Cvarepsilon^(2)` `i=varepsilonsqrt(C/L)=12sqrt((9xx10^(-12))/(2.5xx10^(-3)))=(12xx3)/5 sqrt(10^(-8))` `i=7.2xx10^(-4)A` |
