Question

find equivalent resistance of the network shown in figure between points a and b​

Answer 1

Answer :

Three resistors are connected as shown in the figure. We have to find equivalent resistance between A and B$.$

In these type of questions, first of all we need to simplify the circuit. The best way to simplify any circuit is to apply potential method.

Refer to the attachment for better understanding.

All three resistors are connected in parallel.

So, equivalent resistance will be

⭆ 1/Req = 1/r + 1/r + 1/r

⭆ 1/Req = 3/r

⭆ Req = r/3 Ω
