Question

Two charged conducting bodies $A$ and $B$ having potentials $V_1$and $V_2(>V_1)$respectively are kept far away from each other. Now they are being joined together by a conducting wire. Are the electrons are transferred from $A$ to $B$or $B$ to$A$? Explain your answer.

Answer 1

The electrons will flow from body $A$ to body $B$ as:

1. Potential difference is the amount of work needed to bring a unit charge from one point to other.
2. Charge always flows from high potential to low potential.
3. Electrons flow in the opposite direction of the charge.
4. As body $B\left({\nu }_2\right)>bodyA\left({\nu }_1\right)$ so the charge will flow from ${\nu }_{2}to{\nu }_1$which is body $B$ to body $A$
5. That is electrons will flow from body $A$ to body $B$
