A measure associated with the total resistance to existing circulation in an alternating current circuit, composed of two elements, ohmic weight and reactance, and often represented in complex notation as Z = R + iX, where roentgen is the ohmic opposition and X could be the reactance.
An analogous measure of opposition to an alternating result, as resistance to vibration associated with the method in sound transmission.
A measure of the opposition towards movement of an alternating existing in a circuit; the aggregation of its resistance, inductive and capacitive reactance. Represented because of the representation Z.
a measure of resistance to motion of anything afflicted by a force.
the sound force split because of the particle velocity therefore the surface area by which an acoustic wave propagates.
a measure regarding the resistance brought on by differences when considering two paradigms, especially between object-oriented development and relational databases
The obvious weight in an electric circuit into movement of an alternating present, analogous toward real electric opposition to a direct existing, becoming the ratio of electromotive force to the present. It really is add up to R2 + X2, in which R = ohmic weight, X = reactance. For an inductive circuit, X = 2πfL, where f = regularity and L = self-inductance; for a circuit with ability X = 1 ÷ 2πfC, in which C = ability.
Hindrance; particularly, in electricity, an apparent increase of weight due to induction in a circuit.
Impedance is the evident opposition of an alternating-current circuit, or perhaps the ratio regarding the electromotive force consumed by an alternating present, split because of the present. Because of the electromotive force used by self-induction, the obvious weight with alternating currents is greater than that with direct currents, although power-consumption is the identical. The impedance is comprised of two elements—resistance, which consumes energy, and reactance, the wattless opposition as a result of self-induction. See opposition, 3, and reactance.
a material's opposition towards the flow of electric current; calculated in ohms
