*Three impedances are connected in parallel to a 100 V, 50 Hz supply. The first impedance is(10+ j12.5) Ohms and the second impedance is(20+ j8) ohms. Determine the third impedance if the total current is 20<−25◦ A. 

*What is the impedance value of this equation: (0.025− j0.040) S

*A given load takes 80 kVA at 50% lagging power factor, while another load connected in parallel across the same source takes 40kVA at 86.7% lagging power factor. Find the apparent power. 

*Given Z1= -j2.5 ohms; Z2 = j4 ohms; Z3 = 5 ohms; Z4 = 1+j5 ohms. If the four impedance are connected in series, find the equivalent admittance in mhos?
