Also called chordal or DC resistance This corresponds to the usual definition of resistance; the voltage divided by the current R s t a t i c = V I. {\displaystyle R_{\mathrm {static} }={V \over I}.} It is the slope of the line (chord) from the origin through the point on the curve. Static resistance determines the power dissipation in an electrical component. Points on the current–voltage ...
This means that all pure copper (Cu) wires (which have not been subjected to distortion of their crystalline structure etc.), irrespective of their shape and size, have the same resistivity, but a long, thin copper wire has a much larger resistance than a thick, short copper wire. Every material has its own characteristic resistivity.
One of the functions of many types of multimeters is the measurement of resistance in ohms.. The ohm is defined as an electrical resistance between two points of a conductor when a constant potential difference of one volt (V), applied to these points, produces in the conductor a current of one ampere (A), the conductor not being the seat of any electromotive force.
Materials and components that obey Ohm's law are described as "ohmic" [30] which means they produce the same value for resistance (R = V/I) regardless of the value of V or I which is applied and whether the applied voltage or current is DC (direct current) of either positive or negative polarity or AC (alternating current).
The term negative resistance means negative differential resistance (NDR), / <. In general, a negative differential resistance is a two-terminal component which can amplify , [ 2 ] [ 7 ] converting DC power applied to its terminals to AC output power to amplify an AC signal applied to the same terminals.
Resistance (video game series), a series of alternate history sci-fi shooters developed for Sony video game consoles Resistance: Fall of Man, a Sony PlayStation 3 game; Resistance 2, sequel to Resistance: Fall of Man; Resistance 3, the third game in the main series; Resistance: Retribution, a Sony PlayStation Portable game
Everyday resistance (also, by James C. Scott, called infrapolitics) is a dispersed, quiet, seemingly invisible and disguised form of resistance [1] seemingly aiming at redistribution of control over property. [2] The acts of everyday resistance are considered to be relatively safe and they require either little or no formal coordination. [2]
In these cases, resistance is often used as a metaphor for personal effort or confrontation; a person taking the path of least resistance avoids these. In library science and technical writing, information is ideally arranged for users according to the principle of least effort, or the "path of least resistance". Recursive navigation systems ...
