My notes designed specially for NEET will cover all types of concepts with many solved examples. For NEET a student has to improve speed and practice more and more problems. I cover complete NCERT and relevant questions of HC Verma book, so that complete preparation can be done.

"My daughter is taking coaching for NEET Exam from Rohit sir and she feels fortunate about it. Sir teaches in a very easy and effective way , clarifying doubts then and there. She finds his idea of revising the concepts done in the previous class , before starting the new one , very effective in helping her retain it in her memory for a longer time. Overall, we are very happy with his methods. "

"Sir is the best Physics teacher I have ever had. He helps the student understand the chapter down to its fundamentals rather than simply learning it for the exam, so the student is prepared for all types of questions. He is very patient and understanding of the student's strengths and weaknesses, and accordingly helps them get better in the subject. I highly recommend Rohit Sir, it will be one of your academic life's best decisions. "

We know that Capacitance will change if we insert any dielectric material between the plates. It becomes 'K' times the initial value, where K is the dielectric constant.
Just remember the famous equation Q=CV, now
case-1 when voltage supply remains connected, the potential difference across the capacitor remains unchanged, therefore charge on capacitor has to change and becomes (k times) the initial charge because of capacitance 'C' changes to 'KC'.
Case-2 When the capacitor is disconnected from voltage supply, then the circuit will become open so no charge can flow from one plate to another, hence charge re, mains same in this case and potential difference changes and reduces by a factor of 'K' (Can be easily deduced using the famous equation of Q=CV)
