Learn what voltage is, how it relates to 'potential difference', and why measuring voltage is useful. Voltage , also known as (electrical) potential difference, electric pressure, or electric tension, is the difference in electric potential between two points. [1][2] In a static electric field, it corresponds to the work needed per unit of charge to move a positive test charge from the first point to the second point. In the International System of Units (SI), the derived unit for voltage is the volt (V). [3][4][5] The voltage between points can be caused by the build-up of electric charge (e ... What is Voltage? Electric Potential Difference and EMF Definition & Applications You must have heard of the voltage , current & power that is associated with electricity. It is one of the basic fundamental parameter of electricity. The overhead transmission lines that possess very high voltage used to transmit power over long distance to load center (cities, homes & industries). Any electrical power source such as batteries has its voltage mentioned on its casing such as 12V car batteries or ...
