watts


amps


volts


ohms

Detailed explanation1: Voltage is electric potential energy per unit charge, measured in joules per coulomb ( = volts).
Detailed explanation2: In the International System of Units (SI), electric potential is expressed in units of joules per coulomb (i.e., volts), and differences in potential energy are measured with a voltmeter.
Detailed explanation3: volt, unit of electrical potential, potential difference and electromotive force in the metreâ€“kilogramâ€“second system (SI); it is equal to the difference in potential between two points in a conductor carrying one ampere current when the power dissipated between the points is one watt.
Detailed explanation4: The electric potential, or voltage, is the difference in potential energy per unit charge between two locations in an electric field.
