The action of a capacitor Capacitors store charge and energy. They have many applications, including smoothing varying direct currents, electronic timing circuits and powering the memory to store information in calculators when they are switched off. A capacitor consists of two parallel conducting plates separated by an insulator.
The circuit symbol for a capacitor consists of two parallel lines perpendicular to the wires on either side The charge stored per unit potential Conducting spheres act like capacitors due to their ability to store charge on their surfaces A parallel plate capacitor is made up of two conductive plates with opposite charges building up on each plate
The capacitance of a parallel-plate capacitor is given by C=ε/Ad, where ε=Kε 0 for a dielectric-filled capacitor. Adding a dielectric increases the capacitance by a factor of K, the dielectric constant. The energy density (electric potential energy per unit volume) of the electric field between the plates is:
The larger the area of the plates or the smaller their separation the more charge the capacitor can store. A capacitor is said to be “Fully Charged” when the voltage across its plates equals the supply voltage. The symbol for electrical charge is Q and its unit is the Coulomb. Electrolytic capacitors are polarized.
Q ∝ V; Where Q is the charge and V is the voltage. Q = C V The capacitance depends upon three physical factors, and these are the active area of the capacitor conductor (plates), the gap between the conductors (plates), and the permittivity of the dielectric medium. C = ϵA d C = ϵ A d
