An alternating current of frequency `omega=314s^(-1)` is fed to a circuit consisting of a capacitor of capacitance `C=73 muF` and an active resistance `R=100 Omega` connected in parallel. Find the impedance of the circuit. |

Answer» `(1)/(cancel(Z))=(1)/(r)+(1)/((1)/(iomegaC))=(1)/(R)+iomegaC=(1+iomegaRC)/(R)` `|cancel(Z)|=(R)/( sqrt(1+(omegaRC)^(2)))=40 Omega` |
