Definition of AC and DC PDF 打印 E-mail

Definition of AC
AC stands for "alternating current." The polarity of the electric charge switches from positive to negative, or alternates, at a fixed rate. For typical household current in the United States, the alternation rate is 60 cycles per second.

Definition of DC
DC stands for "direct current." The polarity of the electric charge does not switch back and forth. This is why one end of a battery is positive, and the other end is negative. Current flows from the negative end of the battery, through the device being operated and back to the battery at the positive end.
