In the RL circuit given below, the maximum power will be transferred when value of RL is

In the RL circuit given below, the maximum power will be transferred when value of RL is Correct Answer 15 Ohms 

Concept:

According to maximum power transfer theorem, the maximum will be transferred to load resistance RL when RL is equal to Thevenin resistance Rth

Thevenin resistance is the equivalent resistance across load terminals by replacing all independent voltage sources with short circuit and all independent current sources with open circuit.

Calculation:

After removing all the independent sources, the circuit diagram becomes

Now, Rth = 10 + (10 || 10) = 15 Ω
