The waveform of 230 V and 50 Hz compared with 120 V and 60 Hz. The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user.
Voltages in this article are the nominal single-phase supply voltages, or split-phase supply voltages. Three-phase and industrial loads may have other voltages. All voltages are root mean square (RMS) voltage; the peak AC voltage is greater by a factor of 2 {\displaystyle {\sqrt {2}}} , and the peak-to-peak voltage greater by a factor of 2 2 ...
Mains electricity or utility power, grid power, domestic power, and wall power, or, in some parts of Canada, hydro, is a general-purpose alternating-current (AC) electric power supply. It is the form of electrical power that is delivered to homes and businesses through the electrical grid in many parts of the world.

Andrew Pyper, the Canadian author behind thrillers like Lost Girls and The Demonologist, has died, PEOPLE can confirm. He was 56. The bestselling novelist died of cancer complications on Friday ...
Mains hum, electric hum, cycle hum, or power line hum is a sound associated with alternating current which is twice the frequency of the mains electricity.The fundamental frequency of this sound is usually double that of fundamental 50/60 Hz, i.e., 100/120 Hz, depending on the local power-line frequency.
There weren’t any surprises in the first set of rankings for the 12-team College Football Playoff. Oregon was the No. 1 team ahead of Ohio State, Georgia and Miami.
They discuss all four matchups of Georgia vs. Notre Dame, Arizona State vs. Texas, Boise State vs. Penn State, and Oregon vs. Ohio State. (0:46) Why were there so many blowouts? (37:17) Ryan Day ...
