An impedance ZL = (11.5 + j10) ohms is connected in parallel with an impedance ZC = (8 – j20) ohms. The circuit has a 120 V 60Hz source. Calculate: a) the conductance, susceptance, and admittance of each branch; b) the total conductance, susceptance, and admittance; c) the total current in polar form if the source voltage is used as the reference; d) the total real, reactive, and apparent powers; e) the overall power factor.
