Charging means gaining or losing electron. Matters can be charged in some ways: charging by contact and charging by induction.

Charging by Contact

Charging by conduction engage the contact of a charged object to a neutral object. If a positively charged aluminum plate is touched to a neutral…

The concept of the electric field being null inside of a closed conducting surface was first illustrated by Michael Faraday in 19th century who also considered as a physicist who endorsed the field theory of electricity. Faraday made a closed room, covering the inner room with a metal foil. Inside…

Electricity is a kind of energy that can only be valued by the effects it gives. It is a fundamental part of nature and it is one of the commonly used forms of energy. This word comes from the Greek word elektron which means amber.

Earlier, electricity generation began over 100 years ago, houses…

Gauss surface for a certain charges is an imaginary closed surface with area A, totally adjacent to the charges. It is a method widely used to compute the electric fields form symmetrically charged object.

Gauss’s Law is a common law related to any closed surface. It is an important tool since it…

A periodic wave is a wave with a repeating continuous pattern which determines its wavelength and frequency. It is characterized by the amplitude, a period and a frequency. Amplitude wave is directly related to the energy of a wave, it also refers to the highest and lowest point of a wave. Period…

Three temperature scales are commonly used in science and industry nowadays. These are the Celsius, Kelvin and Fahrenheit.

Degree Celsius (0C)

The degree Celsius (°C) scale was created by separating the scale of temperature between the freezing and boiling temperatures point of…

Waves are known to us from the ocean, the study and theory of sound, and other natural phenomenon.. To completely understand waves, there is a need of understanding of its measurements related with their frequency, wavelength, and their vertical size or amplitude.

Though these measurements aid to…

The Kelvin Temperature Scale

The Kelvin scale of temperature is the generally used in science, particularly in the physical sciences. The Celsius scale is still used a in many areas of physical science, but the Kelvin that is the major SI(International System) unit for temperature. It is to as…

Before the thermometer was introduced, there was the first and closely related thermoscope, a thermometer without a scale. A thermoscope only displayed the differences in temperatures and it displayed something if it was getting hotter or colder. Some inventors created some version of the of it at…

Sound is part of our everyday sensory feelings. We rarely take the time to consider the characteristics and behaviors of sound and the reasons by which sounds are formed, propagated, and detected. Sound is a wave that is created by vibrating objects and propagated through a medium from one location…
