An inductor is also known as a :
Correct answer: A. Low pass filter
- A. Low pass filter
- B. Medium pass filter
- C. High pass filter
- D. None
Explanation
An inductor's reactance (XL = 2πfL) increases with frequency. This means it offers little opposition to low-frequency signals but blocks high-frequency signals, allowing it to function as a low-pass filter.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
