Question

limitations of ohm's law​

Answer 1

Explanation:

The resistance of a material changes when the temperature changes. So when the resistance changes, the ratio of the voltage across the resistor and the current passing through it will not be a constant. We will not get the same numbers always. Non – linear elements and unilateral networks do not support ohm's law.

Answer 2

$\large{\underline {Ohm's}}$$\large{\underline {Law}}$

Definition :- In any electronic circuit the electric current is directly proportional to the voltage and is inversely proportional to resistance.

$fomulae = > v \:= ir$

Denoted by Ω.

Uses :-

• To calculate power, efficiency, current ,voltage & resistance in an electric circuit.

_____________________________________

It's Limitation :-

• It's not applicable for the Unilateral network. Unilateral network allows the current to flow in unidirection or one direction.It consist diode, transistor etc.

• Not applicable for non-linear elements.Non linear elements are the elements in which thier no relationship between current & voltage. eg. thysistors etc.
