The total resistance of three resistances connected in parallel is

20233M#mppsc-forest#pyq#mcq#2023
A.R = R_1 + R_2 + R_3
B.1/R = 2/R_1 + 2/R_2 + 2/R_3
C.R = R_1 × R_2 × R_3
D.1/R = 1/R_1 + 1/R_2 + 1/R_3Correct
Explanation & Solution

Correct Answer: (D) 1/R = 1/R_1 + 1/R_2 + 1/R_3

When multiple resistors are connected in parallel, the reciprocal of the total equivalent resistance is equal to the sum of the reciprocals of the individual resistances, expressed as 1/R = 1/R_1 + 1/R_2 + 1/R_3.

हिंदी में प्रश्न एवं आदर्श उत्तर

समानान्तर में जुड़े तीन प्रतिरोधों का कुल प्रतिरोध है

A.R = R_1 + R_2 + R_3
B.1/R = 2/R_1 + 2/R_2 + 2/R_3
C.R = R_1 × R_2 × R_3
D.1/R = 1/R_1 + 1/R_2 + 1/R_3सही

सही उत्तर: (D) 1/R = 1/R_1 + 1/R_2 + 1/R_3

जब तीन या अधिक प्रतिरोधों को समानांतर क्रम (पैरेलल) में जोड़ा जाता है, तो कुल समतुल्य प्रतिरोध का व्युत्क्रम व्यक्तिगत प्रतिरोधों के व्युत्क्रमों के योग के बराबर होता है: 1/R = 1/R_1 + 1/R_2 + 1/R_3।
