capacitor

[lakshmi]

how does the potential of the conductor decreases when it is charged by a charged body that means if the negative charges are attracted or repeled due to nearby charged body the potential decreases .how is that

Can you please rephrase your question as I fail to comprehend it completely.

Charging a body induces an increase in potential, not decrease. As for the rest of your question, I don't really know what you are referring to.
