In a meter bridge, the point D is a neutral point.

Question:

In a meter bridge, the point D is a neutral point.

(a) the meter bridge can have no other neutral point for this set of resistances

(b) when the jockey contacts a point on meter wire left of D, current flows to B from the wire

(c) when the jockey contacts a point on a meter wire to the right of D, current flows from B to the wire through the galvanometer

(d) when R is increased, the neutral point shifts to left

 

Solution:

The correct answer is

(a) the meter bridge can have no other neutral point for this set of resistances

(c) when the jockey contacts a point on a meter wire to the right of D, current flows from B to the wire through the galvanometer
