Answer:-

  • R1=2ohm
  • R2=4ohm
  • R3=5ohm

We know that

\boxed{\sf \dfrac{1}{R}=\dfrac{1}{R_1}+\dfrac{1}{R_2}+\dfrac{1}{R_3}}

\\ \sf\longmapsto \dfrac{1}{R}=\dfrac{1}{2}+\dfrac{1}{4}+\dfrac{1}{5}

\\ \sf\longmapsto \dfrac{1}{R}=\dfrac{10+5+4}{20}

\\ \sf\longmapsto \dfrac{1}{R}=\dfrac{19}{20}

\\ \sf\longmapsto R=\dfrac{20}{19}

\\ \sf\longmapsto R=1.5\Omega

Given : तीन प्रतिरोध क्रमश: 2,4,एवं 5की समान्तर क्रम में जोड़ा जाता है

To Find :  तुल्य प्रतिरोध की णना

Solution:

तीन प्रतिरोध क्रमश: 2,4,एवं 5

समान्तर क्रम में जोड़ा

Resistance 2 , 4 and 5

Combined in parallel

total resistance​  = R  = तुल्य प्रतिरोध

1/R  = 1/2  + 1/4  + 1/5

=> 1/R  =  ( 10 + 5  +  4) / 20

=> 1/R  = 19/20

=> R = 20/19

total resistance​  = R  = तुल्य प्रतिरोध  = 20/19 Ω
