The correct option is option(B) repeat the experiment by interchanging the resistance in gaps
In a meter bridge experiment, to minimize an error due to contact resistance
In meter bridge experiment, to minimize an error due to contact resistance (A) use non-uniform meter bridge wire (B) repeat the experiment by interchanging the resistance in gaps (C) increase the current flowing through meter bridge wire (D) changing the value of known resistance in the gap
