Inductor is also known as:
Correct answer: A. Low pass filter
- A. Low pass filter
- B. Medium part filter
- C. High pass filter
- D. None
Explanation
In electronics, a low pass filter is a circuit that allows signals with a frequency lower than a certain cutoff frequency to pass through and attenuates frequencies higher than the cutoff frequency. An inductor, due to its ability to resist changes in current, naturally blocks high-frequency signals while allowing low-frequency signals to pass. This makes it suitable for use as a low pass filter in some circuit designs. On the other hand, a high pass filter is not typically associated with an inductor but rather with capacitors in simple RC circuits. The term 'medium part filter' is not a recognized component in electronics.

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.
