Step 1:I'll solve this problem step by step, following the specified formatting guidelines:
Step 2:: Understand the Energy Transformation
In an electric motor, electrical energy is converted into mechanical energy. This occurs through electromagnetic interactions that cause rotational motion.
Step 3:: Analyze the Energy Conversion Process
- The motor receives electrical energy as input - Electrical current creates magnetic fields - Magnetic fields interact to produce rotational motion - Rotational motion represents mechanical energy output
Step 4:: Identify the Correct Energy Transformation
- $$electrical \rightarrow mechanical$$ is the correct transformation
Looking at the given options: - The motor transforms electrical energy into mechanical energy (motion)
Step 5:: Explain the Mechanism
- Electric current flows through motor windings - Creates magnetic fields - Magnetic field interactions cause rotor to spin - Spinning motion converts electrical energy to mechanical energy
Final Answer
The energy transformation that occurs in an operating electric motor is electrical → mechanical energy conversion.
