Two impedances Z1 and Z2 are connected in parallel. The first branch takes a leading
current of 16 A and has a resistance of 5 Ω, while the second branch takes a lagging
current at 0.8pf. The applied voltage is 100+j200 V and the total power is 5 kW. Find
branch impedances, total circuit impedance, branch currents and total circuit current.
