Which of the following statements are true regarding electric generators? Check all that apply. Check all that apply. An electric generator converts mechanical energy into electrical energy. An electric generator creates a time-independent induced voltage. An electric generator creates a time-dependent induced voltage. An electric generator converts electrical energy into magnetic energy. An electric generator is used to increase or decrease an alternating current voltage.

An electric generator creates a time-dependent induced voltage.

An electric generator converts mechanical energy into electrical energy.

Explanation:

An electric generator works on the principle of electromagnetic induction. This phenomenon hinges on the fact that moving a conducting wire through a magnetic field produces electricity. Electricity is generated as long as there is relative motion between the conductor and the magnetic field. The emf generated is known as induced emf or induced voltage.

The electric generator converts mechanical energy to electrical energy.
