Also see current, voltage, and direct current. In electricity, alternating current (AC) occurs when charge carriers in a conductor or semiconductor periodically reverse their direction of movement. Household utility current in most countries is AC with a frequency of 60 hertz (60 complete cycles per second), although in some countries it is 50 Hz. The radio-frequency (RF) current in antennas and transmission lines is another example of AC. An AC waveform can be sinusoidal, square, or sawtooth-shaped. Some AC waveforms are irregular or complicated. An example of sine-wave AC is common household utility current (in the ideal case).
Alternating current is used for long distance transmission because power loss is less that is why the electric current provided in our houses is Alternating current. In direct current the loss of energy is high so it cannot be used for long distance transmission. Rate of recurrence: The frequency of Alternating current varies from country to country. But normally it ranges from 50 Hz to 60 Hz. Frequency of Direct current is persistent. And it shows no variation. Difference between Alternating Current and Direct Current - ResearchPedia.Info. Variation in direction: Alternating current changes its direction in inverse manner. Direct Current streams in only ...
