What is the voltage measured?
In high school, they usually tell what the voltage is measured in. Voltage, or potential difference, is measured in Volts (symbol B, international symbol V). This unit of measurement is consistent with the International System of Units (SI). This name was given to her in honor of Alessandro Volta, the founder of the theory of electricity.
If the magnitude of the voltage is large, they operate on the following derivatives: kilovolts (kV, kV) and megavolts (MV, MV). The latter are used in describing natural phenomena, such as lightning, etc. Voltage measurements in various electrical circuits are of great importance, both in industry and in everyday life. Therefore, there are a huge number of modifications of voltage measuring instruments. But, they all have one common name - voltmeters. They can be both analog and digital. Created for various purposes.
