In the given circuit, the capacitor of capacitance C is charged by closing key K at t = 0. Find the time required to charge the capacitor up to the maximum charge for the given circuit, if it were to be charged with the charged with constant initial charging rate at `t = 0` in the given circuit. A. `RC//3`B. `2RC//5`C. `2RC//3`D. `5RC//3` |

Answer» Correct Answer - D d. Initial charging rate = initial current in the line of capacitor = I `= 2E//5R`. Steady state pd across capacitor is `V_0 = 2/3 E or q_0 = CV_0 = 2/3 EC` `t = q_0/i = ((2//3)EC)/(2E//5R) = 5/3 RC` |
