The impedance of the circuit shown below is?(a) R + jωL(b) R – jωL(c) R + 1/jωL(d) R – 1/jωLThis question was posed to me in a job interview.My question is taken from Impedence Diagram in division Complex Impedence of Network Theory |
Answer» RIGHT OPTION is (a) R + jωL Easy explanation: Impedance is DEFINED as he ratio of the voltage to current function. The impedance of the circuit Z= Vme^tjω/((Vm/(R+jωL)) e^tjω)=R+jωL. |
