Question

Derive an expression for the equivalent resistance, when three resistors of
resistances R1, R2 and R3 are connected in parallel.

Answer 1

Answer:

Given three resistors, which is of resistance R1, R2 and R3

These three resistors are connected in the series of parallel connection.

So, we have to derive an expression for equivalent resistance.

From the given statement we have,

We have R1, R2 and R3

So let us consider

1/R1 + 1/R2 +1/R3 = 1/Rp

Let us add up the given fractions by taking LCM for the denominators and simplify the fraction then we get the solution to be as Rp.
