Save Electricity
★Exhibit Content: Energy conversion, relationship between load and energy consumption ★Interaction: Mechanical interactive operation ★Operation: Press the button to connect one bulb to the generator, turn the handle to light the bulb; then try connecting multiple bulbs and feel that turning the handle requires more effort. ★Exhibit Description: "Saving Electricity" is a desktop science popularization exhibit under the theme of energy education, belonging to the energy and environment science popularization exhibition area, and is a recommended exhibit of the PopsciCat Exhibit Store. This exhibit consists of a hand-cranked generator, multi-channel bulb load wiring components, an operating handle, multiple demonstration bulbs, a curved mounting backboard, etc. By switching the number of bulbs connected to the circuit and manually turning the hand-cranked generator to light the bulbs, visitors can intuitively experience the connection between the load and output energy consumption, personally feel the change in human work after the load increases, understand that the greater the electrical load, the more energy is consumed, establish a life cognition of saving electricity from the experience level, and transform abstract electrical energy consumption knowledge into an intuitive and perceptible interactive experience. ★Scientific Principle: When turning the handle, the human muscles do work to transfer biological mechanical energy to the generator, completing the energy conversion from mechanical energy to electrical energy. The more bulbs connected and lit, the greater the total load of the circuit, the overall energy consumption increases accordingly, and turning the generator requires more effort. When the load decreases, the required input mechanical energy also decreases synchronously, corresponding to reducing the electrical load in real life, which can reduce energy consumption, thereby guiding visitors to establish the scientific concept of saving electricity.
