Formula Sheet — Electrostatic Potential and Capacitance

Important formulas and equations from Electrostatic Potential and Capacitance for CUET (UG) Physics.

Formulas — Electrostatic Potential and Capacitance

Electrostatic Potential

V = W/q₀ = kQ/r
V = (1/4πε₀) × (Q/r)
V₁₂ = V₁ - V₂ = -∫E·dr
E = -dV/dr

Potential Energy

U = qV
U = (1/4πε₀) × (q₁q₂/r₁₂)
U_dipole = -pE cosθ
W = U₂ - U₁

Conductors in Electrostatic Equilibrium

E_surface = σ/ε₀
Pressure = ½ε₀E² = σ²/(2ε₀)

Capacitance and Capacitors

C = Q/V
C_parallel plate = ε₀A/d
C_with dielectric = KC₀ = εA/d
C_sphere = 4πε₀R
