Question:
Rectifier converts:
Rectifier converts:
Updated On: Jul 7, 2022
- mechanical energy to electrical energy
- AC to DC
- light energy to electrical energy
- none of the above
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Rectifier is an electrical conductor that allows current to flow through it in one direction only, thus enabling the conversion of AC to DC. The commonest type of rectifier is the semiconductor diode, which consists of a single p-n junction.
While a photoelectric cell is a device to convert light energy directly into electric energy. While electric generator is a device used to convert mechanical energy into electrical energy.

Concepts Used:
Transformers
Transformer is a device used in power transmission to change the AC voltage without changing the frequency between the circuits. Electrical transformer consists of two coils named as the primary coil and secondary coil which is wounded on a soft iron core. The soft iron core is laminated to minimize eddy currents. Both the coil in the transformer has high mutual inductance.Transformers work on the principle of Faraday’s law of electromagnetic induction and mutual inductions.
A mutual electro-motive force is induced in the transformer from the alternating flux that is set up in the laminated core, due to the coil that is connected to a source of alternating voltage.
Other types of transformers:
- Autotransformers: This kind of transformers contain only one coil wound over a laminated core. In Autotransformers, primary and secondary windings share the same coil.
- Power transformers: They are majorly used in power generation stations as they are suitable for major higher voltages.
