The required concept to solve these questions is the principle of electric generator and mechanical energy.
Use the concepts of electric generator to choose the true statement.
“Mechanical energy is associated with the sum of the potential energy and kinetic energy. It is the energy that depends on the motion and position of an object”.
The device that converts mechanical energy into electrical energy is known as electric generator.
The false statements are as follows:
• An electric generator is used to increase or decrease an alternating current voltage.
• An electric generator converts electrical energy into magnetic energy.
• An electric generator creates a time independent induced voltage.
The electromotive force is produced by changing the number of magnetic flux lines passing through a wire coil in an electric generator. The change of flux lines occurs with respect to the time.
The coil is rotated in a constant magnetic field, which produces an AC voltage.
The mechanical energy of the rotating engine is transformed as electrical engine.
Therefore, the true statement is given below:
An electric generator creates a time-dependent induced voltage.
The coil of the wire is rotated in a constant magnetic field and the rotation occurs by a mechanical engine. The mechanical energy of the rotating engine is transformed as the electrical energy.
Therefore, the true statement is given below:
An electric generator converts mechanical energy into electrical energy.
Ans:An electric generator creates a time-dependent induced voltage is True.
An electric generator converts mechanical energy into electrical energy is True.
