Charge and Coulombs (CC)

Charge is the property of matter that causes force to be exerted in an electromagnetic field. Protons are positively charged and electrons are negatively charged. Charge is measured in coulombs (CC). One coulomb is approximately equal to 6.241509074410186.2415090744 \cdot 10^{18} elementary charges (i.e. electrons or protons). The charge of one electron is therefore 1.6021765651019C−1.602176565 \cdot 10^{−19}C.

Coulombs form the basis for amps, which describe the amount of charge moving past a fixed point per second (the "flow"), and volts, which describe the difference in charge between two points. One coulomb is equal to one amp (AA) per second (ss), or C=A/sC = A/s, and one coulomb is equal to one joule per volt, or C=J/VC = J/V.
