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…

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…

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…

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…

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…

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.…

Introduction Capacitors are small electronic components that can hold an electrical charge, and they’re commonly used in many different types of electrical devices and circuits, such as radios, TVs, microwaves, and computers. When you use capacitors in your electronics projects, you need to be aware of how they work and how they differ from other…

Introduction The tutorial will be focused on an explanation of the definition of both the terms of physics, electric field followed by defining the term named electric potential. The tutorial will discuss how the information of charge at all points can be responsible for developing high electric potential where no electric field can exist. Based…

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…

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…
