Which of the following statements is correct?
- A Silicon doped with boron is an \(n\)-type semiconductor
- B Silicon doped with arsenic is a \(p\)-type semiconductor
- C Metals are good conductors of electricity
- D Electrical conductivity of semiconductors decreases with increasing temperature
Answer & Solution
Correct Answer
(C) Metals are good conductors of electricity
Step-by-step Solution
Detailed explanation
Metals are good conductors of electricity due to the presence of free electrons. Electrical conductivity of semiconductors increases with increase in temperature.
