A fan is connected to a battery in a series circuit. What kind of energy transfer occurs if the circuit is closed?

Question

Responses
A Light energy changes to chemical energy.Light energy changes to chemical energy.
B Thermal energy changes to mechanical energy.Thermal energy changes to mechanical energy.
C Chemical energy changes to mechanical energy.Chemical energy changes to mechanical energy.
D Mechanical energy changes to chemical energy.

Answer 1

In a series circuit with a fan connected to a battery, the energy transfer that occurs when the circuit is closed is:

C. Chemical energy changes to mechanical energy.

The battery stores chemical energy, and when the circuit is closed, this chemical energy is converted into electrical energy which powers the fan, resulting in mechanical energy as the fan blades rotate.
