The regulation of short-term changes in the load resistance of a power supply is called:
- A analog regulation
- B active regulation
- C dynamic regulation
- D static regulation
Correct answer: C — dynamic regulation. From the official ISED question bank, verified word for word.
Why
Dynamic regulation describes how well a power supply handles quick, short-term shifts in the load resistance, keeping the voltage steady even when the current demand changes rapidly. The full explanation — and one for every question — is in Pro.
