In the following R-C circuit, the capacitor is in the steady state. The initial separation of the capacitor plates in x_(0) if at t=0, the separation between the plates starts changing so that a constant current flows through R. Find the velocty of the

The electric curren in a charging R-C circuit is given by i=i_0e^(-t/RC) when i_0 , R and C aere constant parameters of the circuit and t is time. Find the rate of change of current at a. t=0, b. t=RC c. t=10RC .

An AV voltage source is applied across an R-C circuit. Angular frequency of the source is omega , resistance is R and capacitance is C. The current registered is I. If now the frequency of source is changed to omega/2 (but maintaining the same voltage), the current in the circuit is found to be two third. calculate the ratio of reactance to resistance at the original frequency omega .
