Definitions and symbology
2.1. Definitions
Electrical charge:
Charge is the fundamental property of forms of matter that
exhibit electrostatic attraction or repulsion in the presence of other matter. The unit
for electric charge is the Coulomb (C). The Coulomb is defined as the quantity of
charge that passes through the cross section of an electrical conductor carrying one
ampere for one second.
Voltage:
Voltage is the difference in electric potential between two places. It is what
makes electric charges move. The unit for electrical potential difference, or voltage,
is the Volt (V).
Capacitor
: The capacitor is a component which has the ability to store electrical
charge producing a static voltage across its plates.
Capacitance:
Capacitance is the measure of a capacitors ability to store an electrical
charge onto its two plates. The unit for capacitance is the Farad (F). Capacitance is
defined as being that a capacitor has the capacitance of one Farad when a charge of
one Coulomb is stored on the plates by a voltage of one Volt.
