Ohm’s Law

It states that current flowing between two points in a conductor is directly proportional to the potential difference between the two points.

i.e., 1 ∝ V, provided temperature is constant ⇒ v / I = constant (R)

⇒      V = |R

The constant ‘R’ is called resistant of the conductor.

Ohm’s Law is not universal (i.e., all conductors do not obey Ohm’s law.) Conductors obeying Ohm’s law are called Ohmic conductors.
