CBSE Class 12 Physics 2023 Delhi Set 3 Paper

Question : 7

Total: 14

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 ‌

=‌

In the given circuit, ‌

≠‌

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