Question

The circuit diagram given below, the net resistance
between the terminal A and B is
​

Answer 1

To find:

The net resistance between terminals A and B ?

Calculation:

First of all, you can see two plane wires (as shown in diagram).

• Those plane wires will short-circuit the four R resistances. So, we will be left only with two terminal R resistances.

• The middle four R resistances will be neglected.

• Refer to the diagram.

$\therefore \: R_{eq} = R + R$

$\implies \: R_{eq} = 2R$

So, equivalent resistance will be 2R.
