Which of the following statement(s) is/are true regarding null point in finding resistance of unknown wire using meter bridge.
(i) At null point, current through galvanometer is zero.
(ii) At null point, condition is balanced Wheatstone bridge.
(iii) Deflection of galvanometer in same direction, either side of null point.
Text Solution
Verified by ExpertsThe correct answer is:
C
At null point, deflection through galvanometer is zero, also deflection in galvanometer in opposite direction, either side of null point.
