Question

$derivation of parallel resistance ?$
Please Give Answer correctly ​

Answer 1

Answer:

Rtotal = R1R2 / (R1 + R2)

So for two resistors in parallel, the combined resistance is the product of the individual resistances divided by the sum of the resistances. Formula for two resistors connected in parallel.

Answer 2

Answer:

⇒ Replacing I1+I2+I3 by I.

⇒ I = V( 1/R1 + 1/R2 + 1/R3)

⇒ I/V = 1/R1 + 1/R2 + 1/R3
