Q: An electric bulb is connected to a 220V generator. The current is 0.50 A. What is the power of the bulb?
  • A. 440 W
  • B. 110 W
  • C. 11 W
  • D. 44 W
  • E. Not attempted/अप्रयासित
Correct Answer: Option B - प्रश्नानुसार, P = V × I जहाँ, V = विभावंतर = 220V I = धारा = 0.50A, P = शक्ति ∴ P ⟹ 220' × 0.5 ⟹ 110W
B. प्रश्नानुसार, P = V × I जहाँ, V = विभावंतर = 220V I = धारा = 0.50A, P = शक्ति ∴ P ⟹ 220' × 0.5 ⟹ 110W

Explanations:

प्रश्नानुसार, P = V × I जहाँ, V = विभावंतर = 220V I = धारा = 0.50A, P = शक्ति ∴ P ⟹ 220' × 0.5 ⟹ 110W
