Understanding Electrical to Mechanical Energy Conversion
The question asks to identify the equipment that converts electrical energy into mechanical energy. This process involves using electricity to create motion or force.
Analyzing Energy Conversion Devices
- Battery: Stores chemical energy and converts it into electrical energy. It does not produce mechanical energy directly.
- Electric motor: This device is specifically designed to take electrical energy as input and produce rotational or linear mechanical energy as output. It uses electromagnetic principles to achieve this conversion.
- Candle: A candle converts chemical energy (from the wax) into thermal (heat) and light energy. It is not related to electrical or mechanical energy conversion.
- Photo cell: Also known as a photovoltaic cell, it converts light energy (radiant energy) into electrical energy. This is the opposite of what the question asks for.
Conclusion on Energy Transformation
Based on the function of each device, the electric motor is the equipment used to transform electrical energy into mechanical energy.
