	Voltage can be either a direct current (DC), as in the case of the potential difference between the terminals of an electrochemical cell, or alternating current (AC), as in the case of the terminals of a common utility outlet. Direct current maintains the same polarity while in an alternating current it reverses direction periodically. The frequency, measured in hertz (Hz), is the number of cycles per second.
