The energy stored by a capacitor lives in the field between the plates, not the metal.
Capacitance C = q/φ and energy W = Cu²/2. Parallel plates give C = εε₀S/d.
Concentric spheres yield C = 4πε₀ε R₁R₂/|R₂−R₁|; cylinders give C = 2πε₀εℓ/ln(R₂/R₁).
These equations design the electrolytic capacitors that power camera flashes, smooth circuits in phones, and filter signals in medical imaging. Geometry turns empty space into stored energy.
