Power Factor
Power Factor is a measure of how efficiently electrical equipment uses power. Think of it like a car's fuel efficiency rating - the higher the Power Factor, the more efficiently the equipment uses electricity. Electricians and maintenance technicians work to improve Power Factor because it helps companies save money on electricity bills and keeps electrical systems running smoothly. When you see this term in resumes, it usually means the person has experience in analyzing electrical systems and making them more efficient.
