Voltage
Electrical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: The difference in electric potential energy per unit charge between two points in a circuit, which drives charge to flow. It is measured in volts.
Example in context
“The technician measured the voltage across the motor terminals and found it well below the rated value for full-load operation.”
“Teknisyen motor uçlarındaki gerilimi ölçtü ve tam yük çalışması için anma değerinin oldukça altında olduğunu gördü.”
Where engineers use it
Voltage appears in every electrical measurement, design calculation, and safety procedure. Engineers check it when sizing conductors, selecting insulation, diagnosing faults, and verifying that equipment receives the supply level it was designed for.
Synonyms: potential difference, electric tension
Practice: can you use “Voltage” at work?
