Chapter 18 - Electronics - 2

1. When diode is forward biased, the width of its depletion region increases.

2. Central region of the transistor is known as base.

3. The operation in which outputs has value 1 when at least one of its inputs is at 1.

4. Ordinarily electricity is provided to us in the form of direct voltage.
