Volt and ampere are two measures of electrical current or flow of electrons. They define characteristics of an electricity supply. Voltage is a measure of the pressure that allows electrons to flow while ampere is a measure of the volume of electrons. These measurements of supply allow us to calculate the power a supply can deliver.

## Volts

A volt is the unit of electric potential difference or the size of the force that sends the electrons through a circuit. One volt can be describe as the difference in electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points.

### What You Need To Know About Volts

- The volt is named after the Italian physicist Alessandro Volta.
- Volt is the SI unit of electromotive force and potential differences.
- The symbolic representation of volts is
**V**. - The volt is measured by the voltmeter.
- Volt measures the force which causes the electrons to flow through the conductor.
- Measures real power.
- Volts are calculated as Joules per Coulomb,
**V=J/C.**

## Amps

An amp is the unit used to measure electric current. Current is a count of the number of electrons flowing through a circuit. One amp is the amount of current produced by a force of one volt acting through the resistance of one ohm.

### What You Need To Know About Ampd

- Amp is named after the French mathematician and physicist Andre-Marie Ampere, who is considered the father of electrodynamics.
- Amp is the SI unit for current.
- Amp is represented by the symbol
**A**. - Amp is measured by the ammeter.
- Amp measures the rate of flow of electrons.
- Measure apparent power.
- Amps is calculated as Coulombs per seconds,
**A=C/s**
