In this Class 12 Physics topic from Electrostatic Potential and Capacitance, students learn how a parallel plate capacitor stores electric charge and energy between two conducting plates separated by an insulating medium. The topic explains capacitance, the factors affecting it, and the relation C = εA/d, connecting capacitance with plate area, separation, and dielectric material. It also develops understanding of electric field, potential difference, dielectric insertion, charging, and the energy stored in a capacitor through clear concepts and applications.
TOPIC PRACTICE
Up to 1 questions from this page. Select your focus, then start.
The potential energy of a dipole in a uniform electric field is U = −pE cos θ. In the parallel position, the dipole moment is along the field, so θ = 0° and cos 0° = 1. Therefore U = −4 × 6 × 1 = −24 J. Option C is correct. A has the wrong sign, B ignores the interaction energy, and D does not use both physical quantities correctly.
