In the circuit shown switch `S` is closed at `t=0`. Let `i_1` and `i_2` be the current at any finite time t then the ratio `i_1/i_2` A. is constantB. Increases with timeC. Decreases with timeD. first increases and then decreases |

Answer» Correct Answer - B (b) From the given situation `i_(1)= (V)/(R ) (e^(-t//3 RC))` and `i_(2) = (V)/(R ) (e)^((2t)/(3RC))` `(i_(1))/(i_(2)) = (e)^((2t)/(3RC))` Which increases with time. |
