Question

Which of the following statements is correct under forward biased p-n diode?

(a) current enters n side as hole current and leaves p side as electron current

(b) current enters n side as electron current and leaves p side as hole current

(c) current enters p side as hole current and leaves n side as electron current

(d) current enters p side as hole current and leaves p side as electron current

This question was addressed to me in an interview for internship.

This key question is from The Current Components in a P-N junction diode in portion Semiconductor-Diode Characteristics of Electronic Devices & Circuits

Answer 1

Right choice is (c) current enters p side as hole current and leaves n side as electron current

The best explanation: When the current flows in a p-n diode, the current enters p side as hole current and leaves n side as electron current.
