At constant temperature, the current flowing through a conductor is directly proportional to the potential difference(p.d) in volts across the two ends of the given conductor and inversely proportional to the resistance (R) in ohms (Ω) between the ends of the same conductor.

[Ipropto P.D/Rpropto Volts/Ohms]

In all practical problems of electrical calculations, it is assumed that the temperature rise is within limits, so those electrical properties such as insulation and conduction properties of the Given material are not destroyed.Hence Ohm’s Law Mathematically stated as,

[I=V/R]

[V=IR]

[R=V/I]

[I=(V_{R}-V_{Q})/R=V/R (A)]
