An electric fan is plugged into an outlet and the circuit completed, making the fan blades spin. Which of the following correctly describes this situation?

Question

A.
Mechanical energy is transformed into electrical energy.

B.
Electrical energy is transformed into mechanical energy.

C.
Mechanical energy is destroyed, and electrical energy is created.

D.
Electrical energy is destroyed, and mechanical energy is created.

Answer 1

The correct answer is:

B. Electrical energy is transformed into mechanical energy.

In this situation, when the electric fan is plugged in and the circuit is completed, electrical energy from the outlet is used to power the fan, converting that electrical energy into mechanical energy to spin the fan blades.
