An n-p-n transistor can be considered to be equivalent to two diodes connected. The correct figure out of the following is (a) (b) (c) (d)

Step-by-step solution

- In an n-p-n transistor, there are two junctions n-p junction and p-n junction. - So the left side of the base will be an (n-p ) junction and the right side of the base will be a p-n junction. - So, npn transistor = opposite pn diode and pn diode. - And this is shown in option 2. - So the correct answer is option 2.
