Ohm's law state that the amount of pottental difference in a conductor is Directly proportional to the current
V = R * I
Here
V = pottential difference
R = Resistance or constant
I = current

⚫Ohm's law relates potential difference applied across an electrical appliance to the current produced in it....
→According to the Ohm's law←
⚫Current flowing through a conductor is directly proportional to potential difference applied across the ends of conductor, provided physical conditions like temperature etc remains the same...
→Mathematically←
⚫I ∝ v or, v ∝ I .____. => V = IR
where , R is the proportionality constant called the resistance of the conductor. If we plot a graph of V versus (or V—i) then we get a straight line. The slope of the line (v/i) gives the resistance of conductor..
⚫ I – V Graph of a conductor is also a straight line....
