Analysis of AC Circuit
The term ‘Analysis’ stands for detailed examination of something so circuit analysis means carefully breaking down our complex circuit into small parts which makes it easier for us to understand the functioning of our circuit.
In order to analyze the circuit we need to find the currents and voltages values in our circuit. We can employ simple methods to compute these values. We can use ohm’s law to calculate the current in a simple circuit ( voltage by the resistance). The circuit data like angular frequency, and the time are used to compute the ac current.
For a general circuit, the RMS voltage (VRMS) and the frequency (f) of the AC voltage source are provided i.e. given.
Working Principles of Alternating Current Generator
Do you ever wonder what kind of current flows in the power lines of our household? Is it the same current that is generated in electronic devices with DC battery supply or is it something different? In this article, we will discuss a different current that alternates i.e. varies in magnitude and direction. This type of current is called alternating current.
Alternating current is generally seen flowing in power lines(telephone cables, office lines) and normal household electricity that comes from a wall outlet. It is basically used for industrial, chemical, and domestic power usage where it is transmitted over a long distance. The most common frequency for AC power in many parts of the world is 50 or 60 hertz (Hz), meaning the direction of the current changes 50 or 60 times per second. On the contrary, we have DC current which flows in one direction and doesn’t change polarity.
In this article, we will see all the terminologies related to AC current, the method used for generating AC current, and the difference between AC and DC current. We will also discuss the phasors and the application of AC currents. The later part of this article will talk about AC circuit analysis.
