What is Alternating Current?Alternating current is a fundamental aspect of electrical systems that have shaped our world in countless ways. Its ability to be easily generated, converted to different voltages, and transmitted over long distances has made it the preferred choice for power transmission and distribution. Additionally, the many advantages of AC, such as compatibility with various devices and safety features, have made it indispensable in our daily lives.In the world of electricity, t

Now consider an AC circuit with two voltage sources. Here, magnitude, polarity, and phase angle are used to find the equivalent voltage. Electrical Polarity in AC Voltages In the first figure, both sources have the same polarity. Hence, the equivalent voltage is the addition of both. But these are the polar form—First, we need to convert this polar form into a rectangular form. And it will be—Now, the equivalent voltage is the addition of each of the X-components and Y-components (i.e. )—Ag

What is Electrical Resistance?Resistance (also known as ohmic resistance or electrical resistance) is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω).The larger resistance, the greater the barrier against the flow of current.When the potential difference is applied to a conductor, the current starts flowing, or the free electrons start moving. While moving, the free electrons collide with the atoms and

Electricity is the most common form of energy. Electricity is used for various applications such as lighting, transportation, cooking, communication, production of various goods in factories and much more. None of us exactly know that what is electricity. The concept of electricity and theories behind it, can be developed by observing its different behaviors. For observing nature of electricity, it is necessary to study the structure of matters. Every substance in this universe is made up of ext

There are some inventions that changed human civilization. The first invention was the wheel, the second invention was electricity, the third invention was telecommunications, and the fourth invention was the computer. We will discuss the basic introduction of electricity. Each substance in this universe is made of plenty of atoms and each atom has the same number of negative electrons and positive protons.As a result, we can say that each neutral substance has the same number of electrons and p
