Conversion of alternating current into direct current is called:
Correct answer: D. Rectification
- A. Modulation
- B. Amplification
- C. Oscillation
- D. Rectification
Explanation
CONCEPT:Rectification: A rectifier is a device that converts alternating current (AC) into a direct current (DC). This process is called rectification.A p-n junction can be used as a rectifier because it permits current in one direction only.Amplification: The process of increasing the amplitude of the sound wave is called amplification.In this process, we generally increase the volume of the sound.EXPLANATION:According to the definition of amplification, we increase the amplitude of the sound wave.When we increase the amplitude than the volume of the sound increases.So we can say that the process of increasing the sound volume is called amplification. As in the case of rectification, the AC current is converted into DC. Hence option 4 is correct.

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.
