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.
