What is the end error in meter bridge ? How do you remove it? |
|
Answer» Solution :The end error in the METER bridge is due to the FOLLOWING reasons , (i) The zero mark of the scale provided along the bridge wire may not startfrom the position where the bridge wire leaves the copper STRIP and 100 cm mark of the scale may not be at position, where the bridge wire just touches the other copper strip. (II) The resistances of the connecting wires and copper strips of meter bridge have not been taken into account. The end error can be removed by repeating the EXPERIMENT by interchanging the known and unknown resistances and taking the mean of the resistances determined. |
