What Does a Capacitor Do | Explanation | Albert Resources
Capacitance quantifies how much charge a capacitor can store per unit of voltage. The higher the capacitance, the more charge it can store at a given voltage. This is represented in the equation Delta V = frac{Q}{C}, which relates the voltage ( Delta V ) with the charge stored ( Q ) and the capacitance ( C ).
