Which do we do to find the equivalent of resistors in parallel?

a. We sum the inverse of each resistance and then invert the sum

b. We sum the resistances and then invert the sum

c. We sum the inverse of each resistance.

d. We sum the resistances.

We sum the inverse of each resistance and then invert the sum.

Explanation:

The equivalent resistance in case of parallel combination of resistors is given by the formula as :

Here,

R is the equivalent resistance

are individual resistors that are connected in parallel

We can find the value of R as :

So, the correct option is (a) "We sum the inverse of each resistance and then invert the sum".

they start with the same
