Detailed Solution
Download Solution PDFCONCEPT:
- 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 diode can be used as a rectifier because it permits current in one direction only.
- A device that increases the amplitude of the input signal is called an amplifier.
- An n-p-n or p-n-p transistor is used as a transistor to increase the amplitude of the input signal.
EXPLANATION:
- Since a p-n junction diode is used as a rectifier to rectify alternating current.
- That's why in order to rectify an alternating current one uses a diode. So option 1 is correct.
- In an amplifier, indicator, and modulator, a transistor is used. Therefore option 2, 3, and 4 is incorrect.
