Question

When an electric fan plugged into a wall outlet, the blades spin as a result. What energy transformation occurred?

Answer 1

When an electric fan is plugged into a wall outlet and the blades spin, there is an energy transformation from electrical energy to mechanical energy. The electrical energy supplied from the outlet powers the motor, which then converts that electrical energy into mechanical energy to rotate the fan blades. This mechanical energy results in the motion of the blades, producing airflow.
