→About Alternating Currents
*[[Alternating Current|AC]] voltage oscillates in a sinusoidal pattern.
*Frequency of [[Alternating Current|AC]] is 50 [[Hertz|Hz]] or 60 [[Hertz|Hz]] depending on the region.
*[[Alternating Current|Alternating current]] is used for power distribution because it is more efficient over long distances.
*[[Alternating Current|AC]] can be easily transformed to different voltages using [[transformers]].
*The root mean square (RMS) value of [[Alternating Current|AC]] voltage is used to express its effective value.
*[[Alternating Current|Alternating current]] can cause electromagnetic interference (EMI), which needs to be managed in sensitive electronic equipment.*[[Alternating Current|Alternating current]] is generated by [[alternatorsalternator]] s in power plants and is used in [[motors]], [[generators]], and various household appliances.
