The maximum power transfer theorem states that when equivalent source resistance is equal to load resistance the maximum power is being transfer.

It occurs when the magnetic losses equal the copper losses.

We know that transformer is used to transfer power from one circuit to another and also for impedance matching, it happens when "source resistance is equal to load resistance".

The maximum power transfer theorem state that when internal resistance of circuit is equal to load resistance of the circuit.

Ri = Rl.

When the internal resistance is equal to the load resistance then the maximum power will generate according to maximum power transfer theorem.

When the resistance is common for the entire circuit from source to load then power at the source will be equal to power at the load.

P = VI V = IR V is constant that is directly proportional to P.

I and R inversely proportion then power drop at Rs=Rl is high.

Answer is D. When source resistance is equal to load resistance. Proof refer Maximum power transfer theorem in Electrical Circuits.

When the source resistance (RS) is equal to load resistance (RL) then the max power transfer from source to load.
