Question

If equivalent resistance between A and B be R/x, then x will be. Explain ​

Answer 1

Answer:

the value of in the above problem is 3

Answer 2

In these types of complex circuits, first we will try to simplify the circuit by assigning potential drops to each of the resistance.

• Please refer to the diagram.

As you can see , the three resistances are in parallel combination.

$\dfrac{1}{R_{eq}} = \dfrac{1}{R} + \dfrac{1}{R} + \dfrac{1}{R}$

$\implies\dfrac{1}{R_{eq}} = \dfrac{3}{R}$

$\implies R_{eq}= \dfrac{R}{3}$

$\implies R_{eq}= \dfrac{R}{x}$

So, value of x is 3.
