## 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

## 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

## Electric field line

Electric field line Electric field lines are a visual representation of the electric field around an electric charge. In the case of a point charge, it can be expressed in spreading around the charge. The denser the electric field line, … more

## Electroscope

Electroscope Using an electroscope, you can determine whether an object is charged or the polarity of the charge. When the (+) charged body is close to the metal plate, the metal foil’s free electrons are attracted to the metal plate, … more

## Electrostatic Induction

What happens when the charged body is close to the conductor? Electrostatic induction is a redistribution of electrical charge in an object caused by the influence of nearby charges. In the presence of a charged body, an insulated conductor develops … more

## Electrostatic induction (the viewpoint of metal bonding)

What happens when the charged body is close to the conductor? Electrostatic induction is a redistribution of electrical charge in an object caused by the influence of nearby charges. In the presence of a charged body, an insulated conductor develops … more

## Conductor and Insulator

What happens when the charged body is close to the conductor and insulator? ConductorElectrostatic induction is a redistribution of electrical charge in an object caused by nearby charges’ influence. In the presence of a charged body, an insulated conductor develops … more

## What if the water molecule have a straight structure?

The structure of the water molecule Water is a representative ‘polar molecule’. The hydrogen-oxygen-hydrogen bonds that make up the water molecule have an angle of 104.5˚ and appear curved. Because of this unbalanced water molecule structure, the oxygen side has … 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
