The dynamic regulation of a power supply is improved by increasing the value of:
- Athe bleeder resistor
- Bthe output capacitor
- Cthe choke
- Dthe input capacitor
Correct answer: B — the output capacitor. From the official ISED question bank, verified word for word.
Why
Increasing the output capacitor acts like adding a larger water tank to smooth out sudden changes in demand, allowing the power supply to react faster when the load shifts. The full explanation — and one for every question — is in Pro.
