The amplitude of a periodic variable is a measure of its change in a single period (such as time or spatial period). All rights reserved.the state or quality of being ample, especially as to breadth or width; largeness; greatness of extent.the absolute value of the maximum displacement from a zero value during one period of an oscillation.the maximum deviation of an alternating current from its average value.the arc of the horizon measured from the east or west point to the point where a vertical circle through a heavenly body would intersect the horizon.the angular distance along the horizon measured from true east or west to the point of intersection of the vertical circle passing through a celestial body(of a complex number) the angle that the vector representing the complex number makes with the positive real axis.
In older texts, the phase of a period function is sometimes called the amplitude. Published by Houghton Mifflin Harcourt Publishing Company.
In an electrical circuit operating on alternating current (ac), amplitude is measured as the Voltage (V) level and is expressed as +V and V, depending on the direction of the current. Published by Houghton Mifflin Harcourt Publishing Company. It is equal to one-half the length of the vibration path. Definition of amplitude 1 : the extent or range of a quality, property, process, or phenomenon: such as a : the extent of a vibratory movement (as of a pendulum) measured from the mean position to an extreme
amplitude - greatness of magnitude.
magnitude - the property of relative size or extent (whether large or small); "they tried to predict the magnitude of the explosion"; "about the magnitude of a small pea".
