The measure of how much charge can be stored per unit potential difference is known as the capacitance. where C is the capacitance measured in farads (F), Q is the stored charge and V is the potential difference across the terminals of the capacitor. A capacitance of 1 farad is defined as 1 coulomb of charge stored per volt of potential difference.
A capacitor consists of two parallel conducting plates separated by an insulator. When it is connected to a voltage supply charge flows onto the capacitor plates until the potential difference across them is the same as that of the supply. The charge flow and the final charge on each plate is shown in the diagram.
Work is required to store positive and negative charges on the plates of a capacitor, thereby storing Potential Energy in the E-field between the capacitor plates. A graph of the charge building up on the plates, Q, versus time is shown at right. Below that is a graph of ∆V versus Q as the capacitor becomes fully charged.
A capacitor is connected to a power supply and charged to a potential difference V0. Q on the capacitor. At a potential difference V0 a small charge ΔQ is added to the capacitor. This results in a small increase in potential difference ΔV across the capacitor.
By applying a voltage to a capacitor and measuring the charge on the plates, the ratio of the charge Q to the voltage V will give the capacitance value of the capacitor and is therefore given as: C = Q/V this equation can also be re-arranged to give the familiar formula for the quantity of charge on the plates as: Q = C x V
Charge and discharge voltage and current graphs for capacitors. Capacitor charge and discharge graphs are exponential curves. in the above circuit it would be able to store more charge. As a result, it would take longer to charge up to the supply voltage during charging and longer to lose all its charge when discharging.
