Dear Priya Anand,
In electrostatics we have to come across many topics like electric field,potential,capacitance,resistance etc in cases of different types of objects. So there may be a chance of confucing and making mistakes. So go through them thoroughly and by making an image in ur mind u can recollect easily. And question urself on topics and make them clear.
