Dynamo: Mechanical to Electrical Energy Conversion
The question asks to identify the equipment that converts mechanical energy into electrical energy. Mechanical energy is the energy possessed by an object due to its motion or position, while electrical energy is related to the flow of electric charge.
Equipment Function Analysis
- Battery: Stores chemical energy and converts it into electrical energy when needed. It does not convert mechanical energy.
- Photo cell: Also known as a photovoltaic cell, it converts light energy (radiant energy) directly into electrical energy.
- Dynamo: This device operates on the principle of electromagnetic induction. It uses the rotation of a coil within a magnetic field (mechanical input) to generate an electrical current (electrical output). Therefore, it transforms mechanical energy into electrical energy.
- Electric motor: This device does the opposite of a dynamo. It converts electrical energy into mechanical energy, typically used to produce rotation or motion.
Based on the functions, the dynamo is the equipment specifically designed to transform mechanical energy into electrical energy.
