## Definition

a short way of writing 'voltage' in technical fields. It is often used in electronics or physics to describe the electrical pressure in a circuit.

For teachers: a non-standard abbreviation for 'voltage', primarily encountered in technical shorthand or specific industry contexts. While common in certain engineering circles, it is generally replaced by the standard SI unit 'V' in formal documentation.

## Examples

- The technician checked the voc across the battery terminals.
- In the old lab notes, the researcher used 'voc' to record the open-circuit voltage of the solar panel.
- While modern schematics strictly use the letter 'V' to denote voltage, older technical manuals from the mid-century often employed 'voc' as a shorthand for the electrical potential difference.
