In the circuit shown in fig. the capacitor is initially uncharged. Two way switch (s) is placed in position 1 for a very short interval of time (Delta t) and then is moved to position 2. The switch is held in position 2 for equally short interval Delta t and is then moved back to position 1. The process is repeated a large number of times until the charge on the capacitor stops changing. find this final a value of charge on the capacitor. [Assume that in each contact the charge on the capacitor changes by a very small amount] |
