Question

what is mean by Ohm's law ?​

Answer 1

Answer:

According to Ohm's law, the current flowing in a conductor is directly proportional to the potential difference applied across it's ends provided that the physical conditions and the temperature of the conductor remain constant.

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)
