Electronic Devices Question 13
Question: Assertion : Semiconductors do not Obey’s Ohm’s law. Reason : Current is determined by the rate of flow of charge carriers.
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason are both false.
E) If assertion is false but reason is true.
Show Answer
Answer:
Correct Answer: E
Solution:
The assertion is not true.
In fact, semiconductor obeys Ohm’s law for low values of electric field (~ 10^6 V/m).
Above this, the current becomes almost independent of electric field.
