Electrical power is to be transported efficiently from a voltage source with v3(t)=100/2 cos(2r60 t) V through a transmission line of impedance 0.1 + j0.1 N to a load of Z, = 2 +j3 N using an ideal distribution transformer with a = 10 (ratio of turns) and an ideal unit transformer with a' = 1/20 (ratio of turns). a) Draw a schematic diagram of the network. Each transformer should be placed properly in the circuit. b) Find the real power of the load. c) Determine the power efficiency of the system.

plz explain in detail

Electrical power is to be transported efficiently from a voltage source with v,(t)=100/2 cos(260 t) V
through a transmission line of impedance 0.1 + j0.1 N to a load of Z, = 2 + j3 N using an ideal
distribution transformer with a = 10 (ratio of turns) and an ideal unit transformer with a' = 1/20
(ratio of turns).
a) Draw a schematic diagram of the network. Each transformer should be placed properly in the
circuit.
b) Find the real power of the load.
c) Determine the power efficiency of the system.
