Question

The laws of electromagnetic induction have been used in the construction of a :

A

Galvanometer

B

Voltmeter

C

Electric motor

D

Electric generator

Medium

Solution

Verified by  GMS

Correct option is D)

Hint:

The laws of Electromagnetic Induction give us idea about the various ways in which we can produce Electric Current using Electric or Magnetic field.

Correct Option is D.

Explanation for correct answer:

∙  Galvanometer is a device which detects current in the circuit.

∙  Voltmeter is a device which measures potential difference between two points in the circuit.

∙  Electric motor is a device which converts Electrical Energy into Mechanical Energy.

∙  Electric Generator is an device which produces Electric Current from Mechanical energy, Chemical energy, or by using Magnetic or Electric Fields.

The laws if Electromagnetic Induction are used in Electric Generator which produces Electric Current from Magnetic or Electric Fields.
