Web13 hours ago · Formally, we can define alternating current as a form of current that continuously changes its direction at a given frequency. For instance, if we were to attach an ammeter to a circuit wherein AC was flowing, the reading would start from zero, go to a maximum value, then start falling and go to the maximum value in the negative direction. WebOther articles where period is discussed: alternating current: …successive cycles is called the period, the number of cycles or periods per second is the frequency, and the maximum value in either direction is the amplitude of the alternating current. Low frequencies, such as 50 and 60 cycles per second (hertz), are used for domestic and commercial power, but…
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC), which flows only in one direction.
