Determine the value of R for maximum power transfer and find the value of maximum transfer.
(1) Calculation of 𝑉𝑇𝐻
Removing the variable resistor R from the network
Mesh 1 and 2 will form A loop.
Writing current equation for the loop.
Applying KVL to the loop,
From (1) and (2) we get,
𝐼1=−2𝐴 and 𝐼2=2𝐴
Writing 𝑉𝑇𝐻 equation,
8−𝐼1−𝑉𝑇𝐻=0 => 8+2−𝑉𝑇𝐻=0
(2) Calculation of 𝑅𝑇𝐻
Replacing the voltage source by short circuits and current sources by an open circuit
𝑅𝑇𝐻 = 10Ω || 1Ω = 0.91Ω
