The term "60Hz" refers to a frequency of 60 hertz, which means that an event occurs 60 times per second. In the context of electrical systems, it is commonly used to describe the alternating current (AC) frequency in North America. This frequency is important for the operation of electrical devices, as it ensures that they receive a consistent power supply. In video displays, such as televisions and computer monitors, a refresh rate of 60Hz indicates that the screen refreshes the image 60 times per second. This can affect the smoothness of motion in videos and games, making 60Hz a standard for many consumer electronics, including LCD and LED screens.
