Electrostatic Potential and Capacitance — Syllabus & Topics

Topics covered in Electrostatic Potential and Capacitance for J&K CET Physics.

Topics in Electrostatic Potential and Capacitance

1

Electrostatic Potential and Potential Difference

  • Electric potential at a point is the work done per unit charge in bringing a positive test charge from infinity to that point
  • Potential difference between two points is the work done per unit charge in moving a charge from one point to another
  • Electric potential is a scalar quantity with SI unit volt (V) where 1V = 1J/C
2

Potential due to Different Charge Configurations

  • Potential due to point charge: V = kQ/r
  • Potential due to system of charges: algebraic sum of individual potentials
  • Potential due to electric dipole varies with position and angle
3

Potential Energy and Work in Electric Fields

  • Potential energy of two-charge system: U = kq₁q₂/r
  • Work done by electric field is negative of change in potential energy
  • Potential energy of dipole in external field: U = -p⃗·E⃗ = -pE cosθ
4

Capacitance and Capacitors

  • Capacitance C = Q/V is the ability to store charge per unit potential
  • Capacitance depends on geometry and dielectric material, not on charge or voltage
  • Parallel plate capacitor: C = ε₀A/d
