This formula relates the resistance of a conductor with its specific resistance (the Greek letter “rho” (ρ), which looks similar to a lower-case letter “p”), its length (“l”), and its cross-sectional area (“A”). Notice that with the length variable on the top of the fractio...
Silver is the best conductor but due to its high cost, it is not preferred for household circuitry. For most of the household applications, copper and aluminum wires are used as they are less expensive and also provides a suitable conductivity. Resistivity indicates the conducting ability of the...
l is the length of the conductor in meter (m)A is the cross sectional area of the conductor in square meters (m2) It is easy to understand this formula with water pipes analogy:when the pipe is longer, the length is bigger and the resistance will increase. when the pipe is wider, ...
In electronics, the electrical resistance of a conductor signifies the conductor's resistance toward an electrical current flowing through it. In scientific terms, the electrical resistance {eq}R {/eq} is defined as the ratio between the voltage {eq}V {/eq} applied on the conductor and the ...
A resistance element comprising at least a resistance element body comprised of a ceramic including 尾-SIALON of a composition expressed by Si 6-z Al z O z N 8-z (where, in the formula, z=0.3 to 1.0) and an internal conductor embedded inside the resistance element body, wherein the ...
Resistance is a fundamental concept in physics that quantifies the opposition encountered by an electric current flowing through a conductor. It is denoted by the symbol "R" and is measured in ohms (Ω). The resistance of a conductor depends on its mater

Ohm defines the unit of resistance of "1 Ohm" as the resistance between two points in a conductor where the application of 1 volt will push 1 ampere, or 6.241×10^18 electrons. This value is usually represented in schematics with the greek letter "Ω", which is called omega, and ...
