Alternating Current
Alternating current A current that continuously fluctuates in amplitude over time and periodically reverses in direction is known as alternating current OR when compared to direct current (DC), which only travels in one direction and cannot sporadically shift, alternating current (AC) is an electric current that periodically flips direction. Its value is determined at any time by: V= Vmsinωt I= Imsinωt Where, Vm and Im is the peak value of voltage and current graph. Properties of AC current >It includes both positive and negative values. v > The time taken to complete one cycle is known as periodic time. v > Area of positive cycle = area of negative cycle. v > Average value of emf in omh cycle is always zero. RMS (Root-Mean-Square) of an alternating current RMS, or the Root-Mean-Square of current values, is an acronym. RMS value of alternating curren...
