Hz stands for... in electrical terminology.

Hz stands for... in electrical terminology.

• A. Cycles per second
• B. Hand control
• C. Horizontal phase
• D. Polyphase

Answer: (A)

Frequency is measured in hertz, and Hz stands for cycles per second. It describes how often an alternating electrical signal repeats each second. For example, a 60 Hz power supply means the current completes 60 full cycles every second, while 50 Hz is common in many regions. The unit is named after Heinrich Hertz. Hz isn’t about control or phase; the other terms don’t describe the unit of frequency, while polyphase refers to multiple phases in a system, not the meaning of Hz.
