Current Electricity and Electrical InstrumentHard

Question

In the figure a part of circuit is shown :

Options

A.current will flow from A to B

B.current may flow from A to B

C.current will flow from B to A

D.the direction of current will depend on r.

Solution

Potential at C point may be greater than potential at point B. Therefore current flow in resistance may be from B to A.
