Question
What is the unit of frequency?
Answer Options
- A) Hertz
- B) Henry
- C) Farad
- D) Tesla
Correct Answer: A
Explanation
Frequency is the rate at which a repetitive event occurs, such as the number of cycles an alternating current (AC) signal completes per unit of time. The standard international unit of frequency is the Hertz (\text{Hz}), which is defined as one cycle per second.
Amateur radio signals are typically measured in thousands of Hertz (\text{kHz}), millions of Hertz (\text{MHz}), or billions of Hertz (\text{GHz}). The other units listed measure inductance (Henry), capacitance (Farad), and magnetic flux density (Tesla).
