The regulation of long-term changes in the load resistance of a power supply is called:
- A active regulation
- B analog regulation
- C dynamic regulation
- D static regulation
Correct answer: D — static regulation. From the official ISED question bank, verified word for word.
Why
Static regulation measures how well a power supply keeps its voltage steady when the load resistance changes slowly over time, such as when a device warms up or is adjusted gradually. The full explanation — and one for every question — is in Pro.
