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
