Electrostatic Potential and Capacitance | Class 12 Physics | CBSE/NCERT Lecture | HINDI

How much work does it take to bring a charge from infinity to a point? And how do capacitors store charge and energy? In this lecture from The Learning Space, we cover Electrostatic Potential and Capacitance (Class 12 Physics, Chapter 2) with clear diagrams, animations and solved numericals. Electrostatic potential: Potential and potential difference (V = W/q), unit volt Potential due to a point charge (V = kq/r) and a system of charges Potential due to an electric dipole, with derivation Relation between electric field and potential (E = −dV/dr) Equipotential surfaces and their properties Potential energy of a system of charges and of a dipole in a field Conductors and dielectrics: Conductors in electrostatics and electrostatic shielding Dielectrics and polarisation (dielectric constant K) Capacitance: What a capacitor is and how it charges Capacitance C = Q/V and the unit farad Parallel plate capacitor: C = ε₀A/d, and with a dielectric C = Kε₀A/d Factors that decide capacitance: area, separation and dielectric Series and parallel combinations of capacitors Energy stored in a capacitor: U = ½CV² and energy density Practice: 3 solved examples and 3 practice questions Every new topic starts with a definition, then a diagram or animation to build the concept.
