What is resistance?
There are two definition of resistance....
Conceptual definition:
The property of a conductor by virtue of which it opposes the flow of electric current.
Definition of resistance from Ohm’s law:
We know that, mathematical form of ohm’s law,
V=RI
R=V/I
The resistance of a conductor is the ratio of potential difference across two ends of a conductor to the current flowing to the conductor.
What is the SI unit of resistance?
Ohm
