Question

How many electrodes are there in PNP or NPN transistor?

• A. 3
• B. 1
• C. 2
• D. None of these

Answer 1

Answer: (A)

3

In the $\text{NPN}$ OR $\text{PNP}$ transistor, there are $2\text{N -}$part & $1\text{P -}$part and $2\text{P -}$part & $1\text{N -}$part respectively.

SO, there are three electrodes in total.
