During a short circuit, the value of electric current in the circuit:
ಉತ್ತರ ತೋರಿಸು ಮತ್ತು ವಿವರಣೆ
ಉತ್ತರ: (C) Increases very sharply
ವಿವರಣೆ
In a short circuit, live and neutral touch, resistance falls almost to zero and current rises sharply.
- (A) ತಪ್ಪು
Wrong: resistance drops, so current rises.
- (B) ತಪ್ಪು
Wrong: current changes sharply.
- (C) ಸರಿ
Correct: near-zero resistance makes current (I = V/R) very large.
- (D) ತಪ್ಪು
Wrong: the defining feature is a sudden large rise.
