- If a circuit consisted of a resistor
parallel with a capacitor**R**is given an external current excitation with frequency of**C****ω**, let the current equals to, what is the response of voltage*I*0*exp(jωt)? Would the impedance equals to**E****R(1-ωCRj)/(1+ω^2*C^2*R^2),**the same as the case when the circuit is excited by AC voltage**E0*exp(jωt)**?
