Question

If four resistances of each 20 are connected in parallel then what will be the equivalent resistance of the combination​

Answer 1

Answer:

This implies that the total resistance in a parallel circuit is equal to the sum of the inverse of each individual resistances. Therefore, for every circuit with n number or resistors connected in parallel, Rn(parallel)=1R1+1R2+1R3… +1Rn.

Answer 2

Answer:

Hey mate

Here your answer

Four resistance of each = 20 ohms

Resistance in parallel formula = 1/R1 + 1/R2 +1R3+1/R4

= 1/20+1/20+1/20+1/20

= 1/0.2

=5 ohms

5 ohms is the Correct answer
