20192M#mppsc-forest#pyq#mcq#2019
A.Reduces substantially
B.Increases heavilyCorrect
C.Does not change
D.Varies continuously
Explanation & Solution

Correct Answer: (B) Increases heavily

During a short circuit, live and neutral wires come into direct contact, causing the resistance of the circuit to drop nearly to zero. According to Ohm's law, this results in a sudden and massive surge of electric current.

हिंदी में प्रश्न एवं आदर्श उत्तर

शॉर्ट सर्किट के समय परिपथ में धारा का मान :

A.बहुत घट जाता है
B.बहुत बढ़ जाता हैसही
C.नहीं बदलता है
D.लगातार बदलता है

सही उत्तर: (B) बहुत बढ़ जाता है

शॉर्ट सर्किट के दौरान, जीवित और उदासीन तार सीधे संपर्क में आते हैं, जिससे परिपथ का प्रतिरोध लगभग शून्य हो जाता है। ओम के नियम के अनुसार, इसके परिणामस्वरूप परिपथ में विद्युत धारा का मान अत्यधिक बढ़ जाता है।
