fV(femtovolt)

The femtovolt (fV) is a unit of electric potential, which is also known as voltage. It is a part of the International System of Units (SI) and is derived from the base unit of voltage, the volt (V). One femtovolt is equal to 10^-15 volts, or 0.000000000000001 volts.

In the field of electric potential, voltage measures the difference in electric potential energy between two points in a circuit or an electric field. The femtovolt, being such a small unit, is often used to measure very low voltages or potential differences, such as the ones encountered in nanotechnology, sensitive electronic circuits, and biological processes.

µV(microvolt)

A microvolt (µV) is a unit of electric potential, also known as voltage or potential difference. It is a derived unit of the International System of Units (SI) and is equal to one millionth (1/1,000,000) of a volt (V).

In the field of electric potential, voltage is a measure of the electric potential energy per unit charge that exists between two points in an electric field. It represents the force required to move an electric charge from one point to another against the electric field.

A microvolt (µV) is often used in circuits and electronic devices where the potential difference is very small, like in low-power electronic components such as sensors or bioelectronic devices (e.g., measuring brain wave voltage in electroencephalography). It helps to provide precise measurements when dealing with very small voltages.
