The power dissipated by a uniform wire of resistance \(100 \Omega\) when a potential difference of 120 V is applied across its ends is
- A 122 W
- B 144 W
- C 160 W
- D 200 W
Answer & Solution
Correct Answer
(B) 144 W
Step-by-step Solution
Detailed explanation
\(P = \frac{V^2}{R}\) \(P = \frac{(120 \, V)^2}{100 \, \Omega}\) \(P = 144 \, W\)
