How to calculate the resistances of n number of resistors connected in parallel combination?


When n resistors are connected in parallel, finding the equivalent resistance of the resistors.

The total resistance in a parallel circuit is equal to the inverse of the sum of the inverse of each individual resistances. Therefore, for every circuit with n number of resistors connected in parallel,

$R_{parallel}= \frac{1 }{1/R_{1}+1/R_{2}+1/R_{3}…1/R_{n}}$
