Define Electrical Resistance: It is a measure of the opposition or restriction to pass an electric current through an electrical conductor. The resistance of an object depends on material it is made of, and its shape. Electrical Resistance is defined as ratio of voltage(V) difference across its ends and current(I) through it, formulated as R = V / I.
SI unit of electrical resistance is ohm. With Notation as Ω.
We have some handy resistance converters to perform resistance conversions.
