Detailed explanation-1: -Voltage is electric potential energy per unit charge, measured in joules per coulomb ( = volts).
Detailed explanation-2: -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 explanation-3: -volt, unit of electrical potential, potential difference and electromotive force in the metre–kilogram–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 explanation-4: -The electric potential, or voltage, is the difference in potential energy per unit charge between two locations in an electric field.
