Descripción
Electrical resistance, denoted by R, is the total opposition to the passage of electric current, or the flow of electrons. Resistance depends on the material, area, and length of what the current is passing through, so the number varies depending on where resistance is measured. Resistance is measured in Ohms, represented by the symbol Ω. A constant property of a given material is its resistivity, which is defined as how strongly a particular material resists current. Resistivity is denoted by the Greek letter rho, ρ, in the units of Ohm-meters (Ω-m).Here’s a way to calculate the resistance of a given length of wire:
