Question

two limitations of ohms law

Answer 1

There are many limitations of ohm's law, actually disadvantages...... We cannot apply it on 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...... 1) Ohm's law is valid means limited to metal conductors, provided the temperature and other physical conditions remains constant. 2) Ohm's law isn't applicable for gaseous conductors. 3) Ohm's law isn't applicable for semi - conductors such as germanium and silicon. Hope it helps!
