Formula Sheet — Capacitors

Important formulas and equations from Capacitors for JEE Advanced Physics.

Formulas — Capacitors

Capacitance of Conductors

C = q/V
C = 4πε₀R

Types of Capacitors and Their Capacitance

C = ε₀A/d
C = Kε₀A/d
C = ε₀A / (d − t + t/K)
C = ε₀A / (t₁/K₁ + t₂/K₂ + ... + tₙ/Kₙ)
C = 4πε₀(ab)/(b−a)

Energy Stored in Capacitors

U = q²/2C = ½CV² = ½qV
u = ½ε₀KE²
V_common = (q₁ + q₂)/(C₁ + C₂) = (C₁V₁ + C₂V₂)/(C₁ + C₂)
ΔU = C₁C₂(V₁−V₂)² / [2(C₁+C₂)]

Capacitors in Series and Parallel

1/C_eq = 1/C₁ + 1/C₂ + 1/C₃ + ...
C_eq = C₁ + C₂ + C₃ + ...
V₁ = C₂V/(C₁+C₂); V₂ = C₁V/(C₁+C₂)
q₁/q₂ = C₁/C₂ (parallel); q₁ = q₂ = q (series)
