An electric fan is plugged into an outlet in the circuit completed making the fan blade spin which of the following correctly describes a situation A. Electrical energy is transformed into mechanical energy. B. Mechanical energy is transformed into electrical c. Electrical energy is destroyed, and mechanical energy is created. D. Mechanical energy is destroyed, and electrical energy is created.
The correct answer is A. Electrical energy is transformed into mechanical energy.
The correct answer is A. Electrical energy is transformed into mechanical energy.
When the electric fan is plugged into an outlet, it draws electrical energy from the power source. This electrical energy is then converted by the fan's motor into mechanical energy, which causes the fan blades to spin and move the air. Therefore, in this situation, the electrical energy is transformed into mechanical energy.
The correct answer is A. Electrical energy is transformed into mechanical energy.
To understand why this is the case, let's break down the situation step by step:
1. An electric fan is plugged into an outlet, which means it is connected to an electrical circuit.
2. When the fan is turned on, electrical energy flows from the outlet into the fan.
3. Inside the fan, there is an electric motor. This motor contains coils of wire and magnets. When electricity flows through the coils, it creates a magnetic field, which interacts with the magnets and generates a rotational force.
4. This rotational force is then transferred to the fan blades, causing them to spin. As a result, the fan generates a stream of moving air.
In this process, electrical energy from the outlet is being converted into mechanical energy. The electrical energy is being used to create motion, enabling the fan blades to spin and produce the desired effect of moving air. Therefore, option A, "Electrical energy is transformed into mechanical energy," is the correct description.
