What is the term used to describe the difference in voltage between no load and full load on an electrical system?

The term that describes the difference in voltage between no load and full load on an electrical system is known as voltage regulation. This concept is crucial in electrical engineering because it indicates how effectively a power supply can maintain a constant voltage level as the load changes.

When a load is applied to a power supply, there can be a drop in voltage due to the internal resistance of the power source and other factors, such as impedance in the circuit. Voltage regulation quantifies this phenomenon, providing a measure of how much the voltage decreases (or increases, in some cases) from the no-load condition to the full-load condition. A system with good voltage regulation will show minimal voltage variation, which is essential for the stable operation of electrical devices and systems.

The other options do not capture this specific electrical characteristic. Current stability relates to maintaining constant current under varying conditions, while power loss refers to energy dissipation, often due to resistance in the circuit, and load management involves regulating the distribution and usage of electrical loads rather than measuring voltage differences.
