Voltage regulation
What Voltage regulation means in Physics A-Level, as defined for AQA.
Definition of Voltage regulation
Check what you remember
Read the wording for your board, then hide it and explain Voltage regulation in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The circuit acts as a constant voltage source because the Zener voltage changes only slightly as current through it varies.
Topics that use Voltage regulation
- Zener diode (A-level only) (AQA A-Level)

- Current limiting and power dissipation
- Forward bias
- Minimum operating current
- Reverse bias
- Reverse breakdown
