Synopsis of Electrostatic Potential and Capacitance - I


Description: Electrostatic potential measures work done in bringing a unit charge from infinity to a point.


Synopsis of Electrostatic Potential and Capacitance - II


Description: Capacitance is the ability of a conductor to store charge per unit potential difference applied.


Electrostatic Potential due to a (Point Charge & Electric Dipole) - I


Description: Potential due to a point charge decreases inversely with distance from the charge in space.


Electrostatic Potential due to a (Point Charge & Electric Dipole) - II


Description: An electric dipole creates a potential that varies with position and dipole orientation.


Electrostatic Potential due to a (Point Charge & Electric Dipole) - III


Description: Dipole potential depends on angle and distance, highest along axis, zero in equatorial plane.


Equipotential Surfaces & Potential Energy - I


Description: Equipotential surfaces are regions with constant potential, always perpendicular to electric field lines.


Equipotential Surfaces & Potential Energy - II


Description: Work done in moving a charge between equipotentials is zero, conserving electrostatic energy.


Equipotential Surfaces & Potential Energy - III


Description: Closer equipotential surfaces indicate stronger electric fields and steeper potential gradients.


Equipotential Surfaces & Potential Energy - IV


Description: Equipotential surfaces never intersect; they show field direction when combined with field lines.


Equipotential Surfaces & Potential Energy - V


Description: Potential energy arises from charge configuration and changes with movement in electric field.


Equipotential Surfaces & Potential Energy - VI


Description: More potential energy means stronger electrostatic interaction among charges or between system components.


Capacitors and Capacitance & The Parallel Plate Capacitor - I


Description: A capacitor stores energy in an electric field between two conductors separated by insulator.


Capacitors and Capacitance & The Parallel Plate Capacitor - II


Description: Parallel plate capacitors have uniform field; capacitance depends on area and separation distance.


Capacitors and Capacitance & The Parallel Plate Capacitor - III


Description: Dielectric between plates increases capacitance by reducing effective electric field strength inside.


Energy Stored in a Capacitor & Van de Graff Generator - I


Description: Energy stored in a capacitor is proportional to square of voltage across its plates.
