Question

limitations of ohm,s low​

Answer 1

Explanation:

• 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.

• The law is not applicable to unilateral networks. Unilateral networks allow the current to flow in one direction.

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

• The relation between V and I depends on the sign of V.

Answer 2

ANSWER

Limitations of Ohm’s Law of Current Electricity

• The law is not applicable to unilateral networks. Unilateral networks allow the current to flow in one direction. Such types of network consist of elements like a diode, transistor, etc.

• Ohm’s law is also not applicable to non – linear elements. Non-linear elements are those which do not have current exactly proportional to the applied voltage that means the resistance value of those elements changes for different values of voltage and current. Examples of non – linear elements are the thyristor.

• The relation between V and I depends on the sign of V. In other words, if I is the current for a certain V, then reversing the direction of V keeping its magnitude fixed, does not produce a current of the same magnitude as I in the opposite direction. This happens for example in the case of a diode.
