Detailed Solution
Download Solution PDFThe correct answer is Generator.
Key Points
- Electromagnetic induction
- It was first discovered by Faraday’s, therefore, it is also known as Faraday’s laws of electromagnetic induction.
- We know, the generator basic principle of operation, is electromagnetic induction. Hence, Option 3 is correct.
- When a change in flux linkages is changed, an emf or voltage is induced, thus we get voltage and hence current as our output which is desired for generators.
- We know, in generators, the input is mechanical and the output is electrical.
- So, with this change in the magnetic field, we get an induced emf and hence current.
- The mechanical force is used to bring in the changes in magnetic flux which in turn produces electricity.
