If a linear power supply provides overvoltage protection, where is the voltage monitored?
- AAt the output of the filter
- BAt the input of the rectifier
- CAt the input of the transformer
- DAt the output of the regulator
Correct answer: D — At the output of the regulator. From the official ISED question bank, verified word for word.
Why
The voltage must be monitored at the output of the regulator because that is the exact point where the electricity leaves the power supply to reach your radio equipment. The full explanation — and one for every question — is in Pro.
