The power gain of an electrical network is the ratio of an output power to an input power. Unlike other signal gains, such as voltage and current gain, "power gain" may be ambiguous as the meaning of terms "input power" and "output power" is not always clear. Three important power gains are operating power gain, transducer power gain and available power gain. Note that all these definitions of power gains employ the use of average (as oppose of instantaneous) power quantities and therefore the term "average" is often suppressed, which can be confusing at occasions.

Famous quotes containing the words power and/or gain:
“It is only a short step from exaggerating what we can find in the world to exaggerating our power to remake the world. Expecting more novelty than there is, more greatness than there is, and more strangeness than there is, we imagine ourselves masters of a plastic universe. But a world we can shape to our will ... is a shapeless world.”
—Daniel J. Boorstin (b. 1914)
“I find myself ... hoping a total end of all the unhappy divisions of mankind by party-spirit, which at best is but the madness of many for the gain of a few.”
—Alexander Pope (16881744)
