Leyden Jar
Leyden Jar The Leyden Jar is a tool (capacitor) created in the 18th century for storing static electricity. The Leyden Jar is made of glass, with metal foil surrounding the inside and outside of the bottle. The two thin metal … more

Movement of Ion particles
* You can move ion particles with the mouse. Movement of Ion particles Ions acquire electric charge by gaining or losing valence electrons, depending on the type of atom. Electric forces act between charged substances. A pushing force acts between … more
Capacitor Application Circuit
A capacitor is an electronic component made by placing two metal plates close to each other. Capacitors store electrical energy in the form of an electric field. * This simulation only works while pushing with the mouse. * In the … more
The charging and discharging characteristics of capacitor。
Switch up to start charging, and switch down to start discharging. The measured voltage is recorded automatically when charging or discharging starts. You can change the measuring point by moving the probe. For accurate measurement, operate the switch after fully … more
Triboelectricity
When you rub a balloon on a cat, it charged. Charged balloons can be attached to walls or cat. The charged balloon rolls down as it discharges after a certain period of time. Triboelectricity If you peel off a thin … more
Ionic Bond
Formation and energy of the ionic bonds Metal atoms have strong properties to lose electrons and become cations. On the contrary, non-metallic atoms have strong properties to obtain electrons and become anions. As these two particles approach each other, electrons … more
Dielectric in Capacitor
Capacitor A capacitor is an electronic component that temporarily holds charges. The stored charges can work while flowing again. Compared to a river flow, a capacitor can be likened to a dam that holds a river. The capacitor is made … more
DNA electrophoresis
This simulation assumes that the loading dye is 50bp and the marker is 50bp. (‘bp’ is a unit showing the number of base pairs of DNA.) Electrophoresis Electrophoresis is a chemical phenomenon in which an electric charge in a solution … more
Charge Conservation
In the serial circuit, The current is the same everywhere. In the parallel circuit, The current splits up when it comes to a branch. The current in all the branches adds up to the current in the main part of … more
Charge Distribution on a thin Conductive Plate
Charge Distribution on a thin Conductive Plate Charges on the conductor plate are assumed to be (-). The thickness of the conductor plate is assumed to be very thin. Charges on the conductor plate can move freely. Charges of the … more
