The power dissipated across the \(16 \Omega\) resistor in the circuit is 2 watts. The power dissipated in watt units across the \(4 \Omega\) resistor is:
- A 4.28 W
- B 0.64 W
- C 2.38 W
- D 1.28 W
Answer & Solution
Correct Answer
(D) 1.28 W
Step-by-step Solution
Detailed explanation
The circuit consists of two parallel branches. The top branch contains a \(16 \Omega\) resistor. The bottom branch contains a \(6 \Omega\) resistor and a \(4 \Omega\) resistor in series. Let \(V\) be the potential difference across the parallel branches. The power dissipated in…
