Entries found for search: current

alternating current (AC) : An electrical current that periodically changes in direction. The rate of alternation is called the frequency and is measured in cycles per second, or Hertz. Audio signals are always alternating, the frequency corresponding to the pitches of the sounds the signals represent. See Appendix B.

current (I) : The flow of electrical charge measured in amperes.

direct current (DC) : Current in only one direction. DC always has the same direction, from the positive to the negative terminal. Compare with AC.
