AC vs. DC
What is AC?
Short for Alternating Current, AC refers to current that changes in magnitude and polarity (orientation) with time.
It is often expressed in Hertz (Hz), the SI unit of frequency, which is the number of oscillations per second.
What is DC?
DC, which stands for Direct Current, is characterized by current that does not change in polarity over time.
However, there are small changes in magnitude that are also DC, called ripple current.
