Assertion (A): The equivalent resistance between points

A

and

B

in the given network is

2 R

Reason ( $R$ ): All the resistors are connected in parallel

Both Assertion (A) and Reason (R) are true and $(R)$ is the correct explanation of (A).
Both Assertion (A) and Reason (R) are true and $(R)$ is NOT the correct explanation of (A).
Assertion (A) is true and Reason (R) is false.
Assertion (A) is false and Reason (R) is also false.

Solution: 👈: Video Solution

The given resistance network represents in the bridge balance condition, so the equivalent resistance between

A

and

B

will be

2 R

Hence assertion (A) is correct but Reason (R) is false because all resistances are not in parallel.
