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