Question

state Ohm's law with graph and write the type of conductor on the basis of Ohm's Law with example

Answer 1

it states that the current flowing through a conductor is directly proportional to the potential difference across its ends physical conditions remains constant.
on the basis of that it follows ohm's law or not conductors are divided into two kinds:
1.Ohmic conductors.
2.Non ohmic conductors.

Answer 2

According to Ohm's law,

Current flowing in a conductor is directly proportional to the potential difference applied across to its ends at constant temperature & physical conditions.

So, According to the definition

V ∝ I

V/I = constant

Put the constant as “r” which indicates the resistance of the conductor.

R = V/I

V = IR

Where

I = current flowing in the conductor

V = potential difference applied across the conductor

R = resistance of the conductor

Unit of Resistance is called omega (Ω)
