Question

What is Ohm's law? Write any two limitations of it.​

Answer 1

Answer:

The limitations of Ohm's law are outlined below: This law cannot be applied to unilateral networks. A unilateral network has unilateral elements like diode, transistors, etc., which do not have same voltage current relation for both directions of current. Ohm's law is also not applicable for non – linear elements

Answer 2

• Ohm's law, description of the relationship between current , voltage, and resistance .The amount of steady current through a large number of materials is directly proportional to the potential difference, or voltage , across the material. Ohm's law may be expressed mathematically as V/I=R.

• Ohm's law states that current is directly proportional to the voltage and inversely proportional to the resistance of the material.

Limitations of ohm's law

• The law is not applicable to unilateral networks.

• Unilateral networks allow the current to flow in one direction.

• Such types of network consists of element like a diode, transistor, etc.

• Ohm's law is also not applicable to non-linear elements.
