Errors The major systematic errors in this experiment are due to the heating effect, end corrections introduced due to shift of the zero of the scale at A and B, and stray resistances in P and Q, and errors due to non-uniformly of the meter bridge wire. Error Analysis End corrections can be estimated by including known resistances P1and Q1 in the two ends and finding the null point: (where a and b are the end corrections). When the resistance Q1 is placed in the left gap and P1 in the right gap, which give two linear equation for finding a and b. In order that aand b be measured accurately, P1 and Q1 should be as different from each other as possible. For the actual balance point, Errors due to non-uniformity of the meter bridge wire can be minimized by interchanging the resistances in the gaps P and Q. Where d and d are the order of the least count of the scale. The error is, therefore, minimum if = , i.e. when the balance point is in the middle of the bridge. The error in r is To read more, Buy study materials of Current Electricity comprising study notes, revision notes, video lectures, previous year solved questions etc. Also browse for more study materials on Physics here.
