1. Adjustable Discharge Settings: Educational Physics Equipment provides two discharge modes. When connected through the connection plate, it provides coarse static electricity at a slower rate; when disconnected, it provides fine static electricity at a faster rate. 2. Multifunction: Leyden Jar Generator is used to obtain large charges and high voltages (of thousands of volts or so) in electrostatic experiments, and is suitable for a variety of electrostatic experiments. It can be used to study distribution on conductors, electric field lines, tip discharge, vacuum tube discharge, etc. 3. Material: Electrostatic Induction Generator is made of pp material, which is sturdy. The sturdy design ensures longterm use, making it ideal for educational and experimental purposes. 4. : Electricity Generator is equipped with a userfriendly brush design, and the copper wire is mounted on a spring to minimize wear on the charging plate and conductive parts during friction experiments. The large drive wheel and thickened metal crank handle enhance stability.
