Given the parallel circuit shown in Fig. 2, determine the impedance of the series equivalent circuit. 138 - j92 Ohm 200 - j300 Ohm 120 + j85 Ohm 50 - j150 Ohm Given the parallel circuit shown in Fig. 3, determine the impedance of the series equivalent circuit. 324 - j489 Ohm 442 - j257 Ohm 680 + j500 Ohm 238 + j325 Ohm The parallel circuit in Fig. 3 is to be replaced with a parallel circuit that provides a complex conjugate total impedance. Determine the required parallel values. 680 Ohm|| (-j500 Ohm) 500 Ohm|| (j680 Ohm) 500 Ohm|| (-j680 Ohm) 680 Ohm|| j500 Ohm) In a parallel R-L-C circuit like that in Fig. 1, the. Resistor current is in phase with the total source current. Inductor current leads the source voltage by 90 degree. Capacitor current lags the source voltage by 90 degree. Inductor current is 180 degree out of phase with the capacitor current.

Solution

see answer for 11, 12 and 13 are correct

only for 14 the answer is c i.e capacitor current lags the source voltage by 90 degree
