A parallel plate air capacitor of capacitance is connected to a cell of emf and then disconnected from it. A dielectric slab of dielectric constant which can just fill the air gap of the capacitor, is now inserted in it. Which of the following is incorrect?
The energy stored in the capacitor decreases times.
The change in energy stored is
The charge on the capacitor is not conserved.
The potential difference between the plates decreases times.
To solve this problem, let's analyze the situation step-by-step.Initially, the capacitor is charged by a cell of emf The initial charge on the capacitor is given by:The initial energy stored in the capacitor is:
