Voltage is electromotive force or electric potential difference in charge between two points in an electrical field. This potential difference or pressure from electrical power source enables electric circuit to illuminate a bulb.

SI unit of voltage is volt (a joule per coulomb). With Notation as V.

Voltage is measured in volts using an instrument called voltmeter.

Convert a voltage measurement using the conversion calculator below.

Common voltages supplied by power companies to our household usage varies from 110 to 120 volts (AC) and 220 to 240 volts (AC).

Voltage Measurement Units

There are many units of measuring voltage apart from volt. Following is a list of some commonly used electric potential difference units an electronics or electrical engineer should know about.
