Which of the following components are used in a power supply filter network?
Diodes
Transformers and transducers
Capacitors and inductors✓Correct answer
All these choices are correct
Explanation
Filtering works by storing energy between rectifier pulses: capacitors oppose changes in voltage and inductors oppose changes in current, and together they smooth the pulsating rectifier output. Diodes do the rectifying and take no part in the smoothing.
