Final answer:
Charging by conduction occurs when a charged object comes into direct contact with another object, resulting in the transfer of electrons and leading to both objects having the same type of charge.
Step-by-step explanation:
Charging by Conduction Explained
When explaining charging by conduction, it is important to understand that this process involves direct contact between objects to transfer charge. Let's consider a pith ball and a positively charged ebonite rod.
If the pith ball is uncharged or neutral, and the ebonite rod, which has a positive charge, is brought into contact with it, some of the electrons from the pith ball will move onto the rod because unlike charges attract.
This transfer of electrons leads to the pith ball becoming positively charged since it has lost some of its negatively charged electrons.
In contrast, the ebonite rod becomes even more positively charged.
The key concept here is that the direct contact allows for the transfer of charge, and consequently, both objects would end up with the same type of charge after the process.
As another example, consider a metal sphere with excess electrons touched by another with fewer electrons.
Electrons will move from the sphere with more to the one with less until they both have an equal number of excess electrons, illustrating the principle of conduction charging.
