Identify the important features of the semiconductor devices from the following
1. Semiconductor devices require cathode heating for the production of charge carriers.
2. They have long life and high reliability.
3. They are small in size and consume low power.
4. They operate at high voltage.
Choose the correct answer from the options given below:
- A (A) and (D) only
- B (B) and (C) only
- C (A) and (B) only
- D (B), (C) and (D) only
Answer & Solution
Correct Answer
(B) (B) and (C) only
Step-by-step Solution
Detailed explanation
Statements 2\3 are Correct: Semiconductor devices are solid-state, meaning they have no moving parts or filaments. This results in long life, high reliability, small size, and low power consumption. Statement 1 is Incorrect: Unlike vacuum tubes, semiconductors do not need…
