Final answer:
The inductor chosen for a choke input filter offers high impedance to the AC ripple voltage and low impedance to the DC component.
Step-by-step explanation:
The inductor chosen for a choke input filter offers high impedance to the AC ripple voltage and low impedance to the DC component.
Inductors react differently at different frequencies. At higher frequencies, the reactance of an inductor is large, impeding the flow of current and acting as a high impedance.
The inductor chosen for a choke input filter offers high impedance to the AC ripple voltage and low impedance to the DC component. Meanwhile, at lower frequencies, the reactance is small, allowing current to flow easily and acting as a low impedance.
