Leyda’s bottle
Product Code : SCL-ES-12917
The Leyden jar apparatus by Educational Instrument is a classic electrostatics teaching device used to show how electric charge can be stored between conducting surfaces separated by an insulating material. It helps teachers explain capacitance, electric potential, charge accumulation and sudden discharge using a simple, visual laboratory setup.
This product is best suited for structured physics demonstrations with a suitable electrostatic charge source such as a Van de Graaff generator, electrophorus or other approved classroom apparatus.
Key Features
Demonstrates charge storage: Shows how a Leyden jar stores electrostatic charge like an early capacitor.
Supports capacitance lessons: Helps explain charge separation, potential difference and dielectric insulation.
Useful for electrostatics experiments: Suitable for demonstrations of charging, discharging and spark formation.
Classroom-friendly apparatus: Designed for supervised school, college and STEM laboratory demonstrations.
Reusable teaching model: Can be used repeatedly when handled, discharged and stored correctly.
Compatible with physics lab setups: Works with suitable low-energy educational electrostatics equipment.
Clear historical relevance: Connects modern capacitor theory with one of the earliest charge-storage devices.
