Assertion (A): In balanced condition of a Wheatstone bridge, there is no current flow through the galvanometer |
Reason (R): The potential of point B and D are same. |
A) Both A and R are true and R is the correct explanation of A
B) Both A and R are true but R is NOT the correct explanation of A
C) A is true but R is false
D) A is false and R is true
Correct Answer: A
Solution :
Option [a] is correct. |
Explanation: In balanced condition of a Wheatstone bridge, there is no current flow through the galvanometer. This is also called null condition. So, the assertion is true. |
When the potential of point B and D are same then only there is no current flow through the galvanometer. Hence the reason is also true and explains the assertion. |
