pie chartVolt is a unit of electrical pressur. One volt is the amount of pressure that will cause one ampere of current in one ohm of resistance. Different voltages that are typically used in the oilfield in the USA are 480V, 4,160V and 12kV (Kilo Volt).

  • Abbreviated as \(V\) or \(E\)


\(Volts = \sqrt{Watts \;\cdot\; Ohms}\;\; = \;\;V = \sqrt{P \;\cdot\; R}\)

\(Volts = \frac{Watts}{Amps}\;\; = \;\;V = \frac{P}{I}\)

\(Volts = Amps \;\cdot\; Ohms\;\; = \;\;V = I \;\cdot\; R\)
