Which one of the following diagrams depicts the proper flow or electrons and holes in a forward biased p-n junction diode?

Options

A.
B.
C.
D.

Answer

A

Explanation

In a forward biased p-n junction diode, the positive terminal of the battery is connected to the p-side and negative terminal of the battery is connected to the n-side of the diode.
Holes flow from p-side to n-side and electrons flow from n-side to p-side.
