Today’s foundation is the relationship between voltage, current, resistance, and power. These four quantities show up constantly when troubleshooting power supplies, motors, control circuits, semiconductor equipment, and data-center hardware. Voltage (V) is electrical potential difference. Think of voltage as the electrical force available to move charge between two points. A standard U.S. receptacle should measure…
