In the shown meter-bridge circuit, D is the balance point. Select the correct statement(s) about galvanometer-current direction when the jockey is displaced or resistance P is heated. Image

Select all that apply

• Option A

  If the jockey is shifted to the left of D, current will flow from the meter bridge wire to the point B.

• Option B

  If jockey is shifted to the right of D, current will flow from point B to the meter bridge wire.

• Option C

  If the jockey is at point D, but now the resistance P is heated, then the current will flow from point B to the meter bridge wire.

• Option D

  If the jockey is at point D, but now the resistance P is heated, then the current will flow from the meter bridge wire to the point B.
