Find Charge (Q = CV)
Parallel Plate Capacitance
Formula
Q = CV for charge. Parallel plate: C = ε₀εᵣA/d, where ε₀ = 8.854 × 10⁻¹² F/m, εᵣ is relative permittivity, A is plate area, d is separation.
Frequently Asked Questions
What is capacitance?
Capacitance is the ability of a system to store electric charge per unit voltage. It is measured in farads (F). Q = CV relates charge, capacitance, and voltage.
How does a parallel plate capacitor work?
Two conductive plates separated by a dielectric store energy in the electric field between them. Capacitance increases with plate area and permittivity, and decreases with distance.
