NEET Physics (general) MCQ Question
Which of the following statements about capacitors and electrostatic potential is correct?
Inserting a dielectric between capacitor plates increases capacitance while voltage is connected.
An uncharged capacitor connected to a charged capacitor cannot share charge.
The energy stored in a capacitor increases when the voltage supply is disconnected.
The dielectric constant has no effect on the electric field in a capacitor.
Correct Answer
Detailed Explanation
Inserting a dielectric material like mica into a capacitor while it remains connected to a voltage source increases its capacitance due to the dielectric effect, as indicated in the context provided. The other statements contain misconceptions about charge sharing and the effects of dielectrics.
