Voltage
Voltage is the electrical potential difference that drives current through a circuit, measured in volts.
Definition
Voltage is the electrical potential difference between two points in a circuit, measured in volts (V), and is the force that drives current flow. Standard voltages vary by country and application (e.g., single-phase domestic supply versus three-phase industrial supply).
Why It Matters
Voltage is primarily a technical/electrical engineering parameter rather than a direct energy management metric, though voltage quality issues can affect equipment efficiency and lifespan.
