*Standard form of [[electricity]] supplied to homes and businesses.
*[[Alternating Current|AC]] voltage oscillates in a sinusoidal pattern.
*Frequency of [[Alternating Current|AC]] is 50 [[Hertz|HZHz]] or 60 [[Hertz|HZHz]] 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 [[Electrical Transformer|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 [[alternator]]s in power plants and is used in [[motor]]s, [[generator]]s, and various household appliances.
===Examples===
*Household electrical outlets provide [[Alternating Current|AC]] power.
*[[Alternating Current|AC]] is used in power transmission over long distances due to reduced energy loss.
