Here's a good wayto define electromagnetism -Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.The electromagnetic force is carried by electromagnetic fields composed of electric fields and magnetic fields, and it is responsible for electromagnetic radiation such as light.Who Discovered Electromagnetism?In 1820, the Danish physicist, Hans Christian Oersted, discovered that th

What is a Multimeter?A multimeter (MM) is essential for those working with electronics or electrical systems. It is a versatile instrument that combines several measurement functions into one unit, making it indispensable for electricians, technicians, and even DIY enthusiasts. This article will explore a multimeter's features, types of multimeters, and useswhile answering some common questions about this indispensable tool.Multimeters come in two primary forms: digital (DMMs) and analog multime

What is Inductance?Inductance occurs when a change in current flow is exploited for the purpose of preventing signals with a higher frequency component from passing while allowing signals of lower frequency components to pass. This is why inductors are sometimes referred to as "chokes," since they effectively choke off higher frequencies. A common application of a choke is in a radio amplifier biasing circuit where the collector of a transistor needs to be supplied with a DC voltage without allo

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
