    • alternating Specifically, in electricity, periodicaliy reversing or changing the direction in such a manner that the total effect in one direction is the same as in the opposite direction. An alternating current is a current consisting of a series of half-waves of equal duration and equal intensity but opposite direction. One half-wave is called an alternation, two successive half-waves, or a complete wave, a cycle. The number of cycles per second is the frequency. Commercial frequencies are 25, 60, and 125 cycles per second. Since the alternating current varies from instant to instant, the square-root of the mean square of the instantaneous values is commonly employed and called the effective value of the alternating current, since it represents the effect or power of the latter. Under alternating current, alternating electromotive force, etc., usually the effective value is understood. If the successive half-waves gradually decrease in intensity, the current is called an oscillating current. Oscillating currents usually have frequencies of hundred thousands and millions of cycles per second. They are produced by condenser discharges and are used in wireless telegraphy, etc.

By reason foiling passion: you that rave
Of mad alternatives to right and left
Echo the tempter, madam: and 'tis due
Unto your sex to shun it as the grave,
This later apple offered you.

If life with Bent were the alternative.
