"The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose expression in terms of SI base units is s , meaning that one hertz is the reciprocal of one second. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in multiples: kilohertz (kHz), megahertz … " - Hz meaning electrical

WebbNamed after Heinrich Hertz, hertz is a unit of frequency that defines the number of cycles per second of a periodic phenomenon. When applied to monitors, it basically means that 1 hertz = 1 frame per second. The higher the Hz, the more frames your monitor can display per second. How many Hz do you need? WebbBasically a motor or transformer is made by a manufacturer for a specific Hertz or cycles, so either for 50 or for 60 Hz. This is mentioned on the nameplate of the equipment. Sometimes it mentions both Hertz 50 and 60, but this is only for small (low wattage) motors and small transformers.
