Capacitance GapFill

A capacitor is an electrical component which stores charge. Capacitance is defined as  the work done in moving charges acrossthe charge stored per unit potential difference acrossthe potential difference per unit charge stored inthe maximum charge stored by a capacitor. The units of capacitance are  dipolesfaradsteslascoulombs.
Capacitors are made up of a dielectric between two parallel conducting plates. Dielectrics are  any material which resists polarisationa material which is already polarisedelectrical conductors which can be polarisedelectrical insulators which can be polarised. Dielectrics enable the plates to store more charge because  charged molecules rotatepolar molecules rotatecharged molecules are free to moveall molecules remain stationary when an electrical field is applied. For a parallel plate capacitor, the capacitance is given by  C = A²dC = A/dC = AdC = A²/d × ε₀ε_r.
The energy stored by a capacitor is given by E = ½ × QV, which can also be written as  E = ½ × C/V² or E = ½ × Q²/CE = ½ × CV² or E = ½ × Q²/CE = ½ × CV² or E = ½ × Q/C²E = ½ × C/V² or E = ½ × Q²C.
When a capacitor is put in series with a resistor, the charge stored by the capacitor decreases exponentially. The time taken for the charge to decrease by half of its original value is known as the half-life, which is equal to  0.37 R/C0.37 C/R0.37 RC0.69 RC.
