Chapter 18 - Electronics - 9

Physics Class 12
1. Photodiode works in forward biased condition.

2. In transistor size of collector is larger than that of base and emitter.

3. The central reign of transistor is called base.

4. Base is the widest part of transistor.

5. The ratio of collector current to base current is nearly constant for a given transistor.

6. Transistor also act like an amplifier.

7. An operational amplifier cannot be used as comparator

8. Photo voltaic cells mainly consist of operation amplifier by digit ‘o’.
