AC Circuits
Electronics engineering involves the use of different circuits each of which is used for various purposes. One such type of circuit is an alternating current circuit, which forms an integral part of the communication system. In this article, we will study what is an AC circuit and what is the categorization of AC circuits.
We will also study the principle of operation of AC circuits and the components that make up these circuits. We will look at some real-life applications of AC circuits to understand their advantages and disadvantages. We will emphasize the difference between AC and DC circuits as well. The article will conclude with some frequently asked questions.
