Introduction The movement of the charged particles is responsible for electric energy. Energy obtained from the kinetic energy or potential energy of the charged particles is the electric energy. Charged particles are atoms, molecules, or ions that have a charge on them. There is a force of attraction or repulsion between the charged particles which depends on the coulomb’s law. Electricity is an important form of energy. Every matter in the universe attracts other matter with some attractive force. Light is electromagnetic radiation and is the only part of the electromagnetic spectrum that can be visible to the human ... Read More

Introduction Clouds reflect much of the solar radiation in the atmosphere. It prevents the heat from falling on the earth. Therefore, cloudless desert areas have higher temperatures and cloudier areas have lower temperatures. Rain falls when the temperature is above freezing. Rainfall is found in most places on earth. Precipitation occurs only when there is too much moisture in the air. The diameter of a raindrop is more than 5 mm. Humidity is an important factor affecting weather and climate in the atmosphere. As the amount of water vapour in the atmosphere increases, so does the amount of ... Read More

Introduction The dielectric constant is a critical concept which is used in the field of electricity. Different materials have a massive property to hold huge electric charges for long durations. This property of the material is called dielectric. What is Dielectric? A material that has poor electrical conductivity but owns the capability to store an electrical charge is called dielectric material. There are many dielectric materials like vacuum, metal, air or water. It is important to increase capacitance in a circuit of capacitance in those circuits’ dielectrics play a major role. What is Dielectric Constant? The dielectric constant ... Read More

Introduction Electronics have two types of studies; one is when the charge is at rest and another one is when the charge is in motion. Now, what is the charge? A charge is a property of an elementary particle because of which these particles exert or experience a force of attraction or repulsion. Charges are of two types, positive and negative. Also, there is a natural feature or property according to this we can say that when two same charges have equal magnitude but are equal in nature they will repel each other and vice versa. Hence, like repel like ... Read More

Introduction The electric field is a property of charge at rest. The field has a nature whether it is positive or negative, but if it is positive it will repel all positive charges and vice versa. The field may be strong or weak depending on the strength of the charge. However, it can be useful if we want to prevent a system from the external impact of any other field. The electric field of charge at the surface will protect the system inside the surface. We have lots of simple examples of electrostatic shielding like chains hanging on the back ... Read More

Introduction The field of electrostatics dates back to 600 BC. People then already knew about electricity due to the action of friction. But the mathematical formulation of this field of physics happened in the late 18th century with the advent of Coulomb's law of electrostatics. Then the field of electrostatics emerged as a formal field of study. Later with the discovery of Maxwell's equations, it was found that the electric and magnetic fields are two sides of the same coin. In this tutorial, we will ponder the basic electrostatic properties of the conductors and the reasons behind them in ... Read More

Introduction Electricity and magnetism were initially separate subjects. Electricity was related to the charges and magnetism was related to the magnetic materials only. However in the 19th century a Danish physicist, Oersted demonstrated that there is a relation between these two. He found that electric current can create a magnetic field around them. Michael Faraday the British experimental scientist reported one interesting phenomenon. He found that if we move a magnet around a coil connected to a galvanometer, we see deflection in that. The presence of the current in the circuit in such cases implies that an electromotive force gets ... Read More

Introduction Capacitors are components used for two purposes - filtering and coupling. They are powered in a circuit with DC sources to acquire charge and dissipate the charge. Out of four types of capacitors which are discussed in detail in the coming sections, the electrolytic capacitor has a special construction utilizing chemical gel as one of the electrodes. The gel, foil, and dielectric coating of aluminum oxide design help to provide a high capacitance value with minimum size. This article conveys the general concepts of capacitors with a focus on electrolytic capacitors. It is important to note that alternate current ... Read More

Introduction Every matter in the universe is made up of molecules. So, many atoms contain both positively charged and negatively charged. This force of attraction is known as a chemical bond. This bonding occurs due to electrostatic force between oppositely charged ions or by sharing of electrons. Formerly called ionic bond and later called a covalent bond. The polarity of the molecules depends upon the bonding between them. The movement of the charged particles is responsible for electric energy. Energy obtained from the kinetic energy or potential energy of the charged particles is the electric energy. Charged particles are atoms, ... Read More

Introduction With the use of capacitors in parallel and in series, it’s possible to create capacitors with different properties and functions. As electric current flows through a capacitor, it creates an opposing charge on each of its plates. As you might guess, each electrode attracts opposite charges that are equal and opposite of one another. What are they, how do they work, and why would you want to use them? This tutorial will cover all the basics you need to know about capacitors in parallel as well as offer some suggestions on how to use them in your next project. ... Read More
