Question

A and B are two metal spheres which are connected with the help of a metal

wire. State the direction of flow of electrons in each case​

Answer 1

Answer:

As electron is negatively charge therefore in first case it will move from a to b

In second case electron will move from b to a

Answer 2

The flow of electrons in case 1 is from A to B and in case 2 is from B to A.

• The sphere B in case 1 has a lesser number of electrons. So the movement of electrons is from A to B in case 1.
• But the sphere A with a positive charge in case 2 has a lesser number of electrons. So the movement of electrons is from B to A in case 2.
• The movement of electrons is usually from lower potential to higher potential.
