R=Resistance (which is a constant)
ohm’s law is represented by a graph:-
Here question arises what is a Resistance. So,
let’s do a question on resistance:-
The potential difference between two points of a wire carrying a 2 amperes current is 0.1 volt. calculate the resistance between these points?
from ohm’s law we have:
Here, Potential difference,V=0.1 Volt
putting these values in the above formula, we get:
or Resistance,R=0.05 ohm or (0.05 Ω).
