Product Code : SCL-PLE-11362

Scientifc Equipment Leyden Jar is an educational electrostatics apparatus designed to demonstrate the storage of electric charge, capacitance, static electricity, charge accumulation, and discharge. It is suitable for school physics laboratories, STEM classrooms, college practical labs, science demonstrations, and teacher-led experiments on electrostatic energy.

The Leyden Jar is one of the earliest forms of a capacitor and is widely used in physics education to help students understand how electric charge can be stored on conducting surfaces separated by an insulating material. It provides a clear practical demonstration of capacitance, potential difference, charging, and discharging in electrostatics.

Product Description

The Leyden Jar by Scientifc Equipment is a classic laboratory apparatus used for demonstrating charge storage in electrostatics. It generally consists of a glass or insulating jar, inner and outer conducting coatings, a metal rod, metal knob, and conducting chain or contact arrangement as per supplied model configuration.

When the metal knob is connected to a charged source such as an electrostatic generator, charge accumulates on the inner conductor while an opposite charge is induced on the outer conductor. The insulating jar acts as a dielectric between the two conducting surfaces, allowing the apparatus to store electric charge temporarily.

Scientifc Equipment Leyden Jar is useful for teaching capacitance, electrostatic charge storage, discharge sparks, dielectric function, electric potential, and the basic working principle of capacitors in a simple and visual way.
