What is the unit of measure for electrical frequency?

• A. Watts
• B. Hertz (Hz)
• C. Amperes
• D. Ohms

Answer: (B)

The unit of measure for electrical frequency is Hertz (Hz). Hertz defines how many cycles of electrical current or signal occur in one second. For example, standard residential electrical systems operate at either 50 or 60 Hz, which means the alternating current (AC) changes direction 50 or 60 times each second. Understanding frequency is essential in various applications, including power generation, telecommunications, and signal processing, as it influences the behavior and efficiency of electrical systems. While Watts are a measure of power, Amperes are a measure of current, and Ohms refer to resistance, none of these represent frequency. Hence, Hertz is the appropriate and correct unit in the context of electrical frequency.
