A diode can convert
Correct answer: A. ac into dc but not dc into ac
- A. ac into dc but not dc into ac
- B. ac into dc and dc into ac
- C. dc into ac but not ac into dc
- D. neither ac into dc nor dc into ac
Explanation
A diode can rectify alternating current (AC) into direct current (DC) but does not perform the reverse operation. It allows current to flow in one direction (from anode to cathode) and blocks it in the reverse direction.Incorrect Options and Explanations: (b) ac into dc and dc into ac - A diode does not convert DC into AC; it only rectifies AC into DC. (c) dc into ac but not ac into dc - A diode is not designed to convert DC into AC. (d) neither ac into dc nor dc into ac - A diode can convert AC into DC.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
