Marks: +1, -0

Assertion (A): The given figure does not show a balanced Wheatstone bridge.

Reason (R): For a balanced bridge small current should flow though the galvanometer.

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

Balance condition of Wheatstone bridge is

\;{P}/{Q}=\;{R}/{S}

In the given circuit,

\;{P}/{Q} ≠ \;{R}/{S}

.
So, the assertion is true.
Since, the given bridge is not in balanced condition, so current will flow in the galvanometer.
