Answer 1

Answer:

hii mate....

Resistance is the hindrance offered by an object to the flow of current through it. ... SI unit of resistance is Ohm (Ω). It is resistance offered by an object when 1 volt potential difference is applied across it and 1 Ampere of current passes through it.

Answer 2

Answer:

resistance

Explanation:

The electrical resistance of an object is a measure of its opposition to the flow of electric current. The inverse quantity is electrical conductance, and is the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with the notion of mechanical friction.
