Short Answer

High-frequency noise in AC power can damage computers. Does the plug-in unit designed to prevent this damage use a large inductance or a large capacitance (in series with the computer) to filter out such high frequencies? Explain.

To prevent high-frequency damage, it uses a huge inductance in series with the computer.

Step 1: Definition of frequency, inductor and capacitor

The number of times a repeated event occurs per unit of time is known as frequency. It's also referred to as temporal frequency to distinguish it from spatial frequency, and ordinary frequency to distinguish it from angular frequency.

The majority of power electronic circuits include inductors, which are passive parts that store energy in the form of magnetic energy when electricity is applied to them. A significant characteristic of an inductor is that it resists changes in the amount of current that passes through it.

A capacitor is an electrical energy storage device that operates in an electric field. It's a two-terminal passive electrical component. Capacitance is the term used to describe the effect of a capacitor.

Step 2: Explanation

A substantial inductance is used in series with the computer in the plug-in unit designed to avoid harm from high-frequency noise.

A high-frequency filter is a large inductance connected in series that filters out high frequencies that could harm the computer while allowing only low frequencies to get through.

Step 3: Apply the formula

Take a look at the formula for inductive reactance to see why huge inductance is used:

\({X_L} = 2\pi fL\)

Inductive reactance is proportional to frequency and measured in ohms \(\Omega \).

As a result, as the frequency rises, so does the inductive reactance, which can be thought of as the inductor's resistance to high frequencies.
