In the shown circuit involvinga resistor of resistance R Omega, capacitor of capacitance C farad and an ideal cell of emf E volts, the capacitor is initiallyuncharged and the key is in position 1. At t = 0 second the key is pushedto position 2 for t_(0) = RC seconds and then key is pushed back to position 1 for t_(0) = RCseconds. This process is repeatedagain and again. Assume the time taken to push key from position 1 to 2 and vice verse to be negligible. The current through theresistanceat t = 1.5 RC seconds is |
