Earth's Revolution and Seasons

Earth’s Revolution and Seasons (WebGL)

Earth Rotation and Seasonal Changes The Earth’s rotation axis is tilted at an angle of about 23.5 ° to the orbital axis. Because of this inclination, seasonal changes occur like spring, summer, autumn, and winter. The … more

AC Power Generator

AC Power Generator

Electromagnetic induction Moving a magnet around a coil changes the magnetic field inside the coil, which causes current to flow through the coil. This phenomenon is called ‘electromagnetic induction’; the current flowing through the coil is … more

Home wiring

Home Wiring (Indoor Wiring)

Covalent Bonds of Hydrocarbon

Why are the outermost electrons of atoms important? The outermost electrons of an atom are essential indicators of the properties of matter. Period 2 and 3 elements, such as carbon, oxygen, and nitrogen can exist in … more

Incandescence

Incandescent light bulb (heat dissipation of resistance)

Resistance Materials have different degrees of impeding the flow of electric current depending on their type and shape. Most materials, except metals, do not conduct current well. On the other hand, metals have low resistance and … more

Capacitor Application Circuit

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 … more

Law of Definite Proportions

Law of Definite Proportions

Law of Definite Proportions In a reaction where hydrogen gas is burned to produce water, two hydrogen atoms combine with one oxygen atom. Hydrogen gas and oxygen gas always react in a ratio of 2:1 to … more
