Question

28. Explain the charging by conduction in terms of movement of electrons.​

Answer 1

Explanation:

Place rod A on an insulating stand and bring positively charged conductor Rod B near the rod A and touch it. The charge from rod B is transferred on Rod A till they both have a similar charge.

Suppose A has 10 protons and 10 electrons and B is positively charged is deficient in electrons having 20 electrons and 30 protons. On touching B with A, 5 protons are transferred to A

Now, A and B both have 5 protons in excess and have positive charge of 5 protons.
