उत्तर दाखवा आणि स्पष्टीकरण
उत्तर: (C) Increases very sharply
स्पष्टीकरण
In a short circuit, live and neutral touch, resistance falls almost to zero and current rises sharply.
- (A) चूक
Wrong: resistance drops, so current rises.
- (B) चूक
Wrong: current changes sharply.
- (C) बरोबर
Correct: near-zero resistance makes current (I = V/R) very large.
- (D) चूक
Wrong: the defining feature is a sudden large rise.
