The term for the permissible voltage decrease under load is called:

• A. Voltage Drop
• B. Nominal Voltage
• C. Amps
• D. Battery Charger Testing

Answer: (A)

Voltage can sag from the source to the point where the load is connected because the wiring and components have resistance and impedance. The drop in voltage that occurs under load is called the voltage drop. It represents the permissible decrease allowed so that equipment still receives enough voltage to operate correctly, with the exact limit depending on standards and the specific system. Nominal voltage is the rated voltage of the system without considering losses under load. Amps measure current, which influences how big the voltage drop will be but isn’t the term for the drop itself. Battery charger testing relates to evaluating charging performance, not the voltage sag along the circuit.
