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. … more
Static Electricity Simulation
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 … 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 … 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 … 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, … 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, … 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, … 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, … 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 … more
