Volt Amp Meter Key Terms
Understand the ABC's of volt amp metersA volt amp meter (also known as a multimeter) is an electronic device that measures the total voltage and current in an electrical circuit.
While interacting with professionals or service providers from the electrical industry, you will come across various technical terms that state the types, units and specifications of volt amp meters. This guide will familiarize you with the key terms of volt amp meters, such as AC, DC, ampere, ohm, volt-amp resistance, digital and analog voltmeters.
AC (Alternating Current)
DC (Direct Current)Direct current is a current with unidirectional flow that a storage battery or electromagnetic induction produces.
Digital voltmetersA digital voltmeter gives an accurate measurement of the voltage potential between two points in an electrical circuit.
Analog voltmetersAn analog voltmeter is the traditional measuring device. It measures the voltage or voltage drop in an electrical circuit.
OhmOhm is the derived unit of electrical resistance as per the SI (Systeme Internationale) standards. One ohm is defined as the resistance between two points that requires one volt of potential difference to produce one ampere of current.
AmpereAn ampere is the SI (Systeme Internationale) unit of electric current that is equal to one coulomb per second.
NIST Physics Laboratory, a service provider for the electronic, optical and radiation industry.
Volt-amp resistanceVolt-amp resistance is the unit to measure reactive power of an electronic circuit.
Diode testingDiode testing is an important function of a volt amp meter. It tests the resistance of diodes in forward and backward directions. Some volt amp meters have special diode testing range incorporated in the device.
