It is a property of a conductor by virtue of which the passage of current is opposed, causing electric energy to be transformed into heat: equal to the voltage across the conductor divided by the current flowing in the conductor.

Its SI unit is ohms.It is the electrical resistance between two points of a conductor when a constant potential difference applied between these points produces in this conductor a current of one ampere.

Hii There!!

<> Resistance is the relationship between potential difference and electric current generated. High resistance needs a large potential difference to generate an appreciable current. Electrons will generally flow through the path with the least resistance.

The standard unit of resistance is the ohm,sometimes symbolized by the letter omega Ω
