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?
Electrical energy is transformed into mechanical energy.
Mechanical energy is transformed into electrical energy.
Mechanical energy is destroyed, and electrical energy is created.
Electrical energy is destroyed, and mechanical energy is created.
The correct description is: Electrical energy is transformed into mechanical energy.
no
The correct description of this situation is: Electrical energy is transformed into mechanical energy.
The correct answer is: Electrical energy is transformed into mechanical energy.
To understand why, let's break it down step by step:
1. When the electric fan is plugged into the outlet, it is connected to an electrical circuit. The outlet provides a source of electrical energy.
2. When the circuit is completed by plugging in the fan, the electrical energy from the outlet flows into the fan.
3. Inside the fan, there is an electric motor, which is responsible for converting the electrical energy into mechanical energy.
4. The motor uses the electrical energy to create a magnetic field, which interacts with magnets and causes the fan blades to spin.
5. As a result, the electrical energy is transformed into mechanical energy as the fan blades rotate, which produces the desired cooling effect.
So, in this situation, the electrical energy from the outlet is converted into mechanical energy by the electric motor in the fan.
