Principle
Electrical
Theory
AC or alternative current came about as the interaction of magnets and electricity were discovered. In an AC circuit,the current repetively changes direction every so often.That means current increases in flow to a peak, then decreases to zero current flow, then increases in flow in the opposite direction to peak, then back to zero, and the whole process repeat. The current alternates the direction of flow in a sinusoidal fashion,so of course it is called alternating current. This type of current most commonly comes from big AC generators at yours local hydroelectric dam.AC power came into being due to this ease of generation,when you move a coil of wire past a magnet,the current first climbs as the strength of the field increases, then as the field decreases and switches polarity.The voltage and current change in a sinusoidal fashion naturally as the coil passed by the magnets.
Conclusion
Alternative Current is an electric current, alternative current is from in which electric power is delivered to businesses and residences, and it is the from of electrical energy that consumers typically use when they plug Kitchen appliances television,fans,and electric lamps in to wall sockets.
