Question

For the given circuit, during maximum power transfer, the value of \(R\) and the magnitude of the power delivered to \(R\) are

• A. \(5~\Omega\) and \(1~W\)
• B. \(15~\Omega\) and \(10~W\)
• C. \(2.12~\Omega\) and \(1.233~W\)
• D. \(5.33~\Omega\) and \(0.188~W\)

Hint:

For maximum power transfer problems: \[ R_L=R_{th} \] and \[ P_{\max}=\frac{V_{th}^{2}}{4R_{th}}. \] Always find the Thevenin equivalent seen from the load terminals before applying the theorem.

Answer 1

The Correct Option is D
