Question

When a forward biased is applied to a diode, the electrons enter to which region of the diode?

(a) P-region

(b) N-region

(c) P-n junction

(d) Metal side

The question was posed to me by my school principal while I was bunking the class.

My doubt stems from The Current Components in a P-N junction diode topic in section Semiconductor-Diode Characteristics of Electronic Devices & Circuits

Answer 1

Correct answer is (a) P-region

To explain I would say: When the forward biased is applied, the electrons enter to the p-region and the holes enter to the n-region so that holes can flow from p-region to n-region. Whereas, the electrons can travel from n-region to p-region.
