Variables in Circuits - Customization of Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction to Scientific Principles:

exhibits provide variable operations in voltage, current, electric power, etc., and the audience observes the results by changing the corresponding variables. The characteristics of a circuit are described by physical quantities such as current, voltage, and electrical power. exhibits simulate home circuits by changing variables in voltage, current, and electrical power to observe the brightness of light bulbs and the speed of fans.

Main technical parameters of exhibits:
