Question

Pick the correct answer from the following two statements :

1. Ohm's law is applicable to semiconductors.
2. Ohm's law is applicable to metallic conductors.

• A. Only (a) is true
• B. Only (b) is true
• C. Both (a) and (b) are true
• D. Both (a) and (b) are false

Answer 1

The Correct Option is B

Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it, provided the temperature and other physical conditions remain constant. 

This law is applicable to metallic conductors under constant physical conditions. 
Semiconductors do not strictly obey Ohm's law due to their non-linear behavior. 

Therefore, only statement (b) is true.
