31Electrical resistivity and conductivity — This article is about electrical conductivity in general. For the specific conductance of aqueous solutions, see Conductivity (electrolytic). For other types of conductivity, see Conductivity. Electrical resistivity (also known as resistivity,… …
32Mason's invariant — In electronics, Mason s invariant, named after Samuel Jefferson Mason, is a measure of the quality of transistors. When trying to solve a seemingly difficult problem, Sam said to concentrate on the easier ones first; the rest, including the… …
33reactance — /ree ak teuhns/, n. 1. Elect. the opposition of inductance and capacitance to alternating current, expressed in ohms: equal to the product of the sine of the angular phase difference between current and voltage and the ratio of the effective… …
34Ohm's law — This article is about the law related to electricity. For other uses, see Ohm s acoustic law. V, I, and R, the parameters of Ohm s law. Ohm s law states that the current through a conductor between two points is directly proportional to the… …
35siemens — (S) the SI unit of electric conductance, susceptance, and admittance. The most important property of a conductor is the amount of current it will carry when a voltage is applied. Current flow is opposed by resistance in all circuits, and by… …
36Complex number — A complex number can be visually represented as a pair of numbers forming a vector on a diagram called an Argand diagram, representing the complex plane. Re is the real axis, Im is the imaginary axis, and i is the square root of –1. A complex… …
37Resistor — A typical axial lead resistor Type Passive Working principle Electrical resistance Invented Ge …
38Electrical conductance — is a measure of how easily electricity flows along a certain path through an electrical element. The SI derived unit of conductance is the siemens (also called the mho , because it is the reciprocal of electrical resistance, measured in ohms).… …
39Electrical resistance — is a ratio of the degree to which an object opposes an electric current through it, measured in Ohms. Its reciprocal quantity is electrical conductance measured in Siemens. Assuming a uniform current density, an object s electrical resistance is… …
40Q factor — For other uses of the terms Q and Q factor see Q value. In physics and engineering the quality factor or Q factor is a dimensionless parameter that compares the time constant for decay of an oscillating physical system s amplitude to its… …
