Question

Ohm's law is not applicable to option A) DC circuit b) high current c)small resistor d)semi conductor

Answer 1

Answer:

it is not applicable to semiconductors

Explanation:Ohm's Law DOES NOT apply to most semiconducting devices, because they are not linear or ohmic -that is the ratio of voltage to current doesn't remain constant for variations in voltage. ... The so-called 'Ohm's Law formula' (R = E/I) is actually derived from the definition of the ohm, and NOT from Ohm's Law!

Answer 2

D ....but V=IR is valid don't get confused
