Electrical Circuit Analysis

Today everybody takes electricity for granted but it wasn’t that long ago that electricity was first invented and prior to that time, life was very different. Although words that are seen in everyday life today, like volts, amperes and watts, these words did not exist in the days before electricity, well, not as anything apart from names. It was the Scottish inventor James Watt that first invented the notion of electricity after his famous work with steam engines in the early 1800s. Soon after that, the Italian professor Alessandro Volta invented the first battery which was able to provide a steady current of electricity. The ability to measure electricity has been credited to the French teacher André-Marie Ampère but it was the German physicist George Ohm that discovered how to distinguish between current and voltage by measuring resistance. All these people have become household names although many today do not realize their significance and do not give them a second thought. Perhaps a name more popularly associated with electricity is Thomas Edison as he has often been credited with inventing the first light bulb but, in actual fact he didn’t, he merely bought the patent from a couple of Canadian students named Henry Woodward and Mathew Evans who could not afford to develop their idea further. It is true however that Edison did improve on the student’s original concept and it was by reversing Edison’s theory which led Nikola Tesla to invent the first electric motor.

In those early days electricity almost seemed like magic to most people but as mentioned, it has now become something that we often take for granted and find ourselves lost without it. Electricity has today become something that many of us cannot do without; we use it all the time whether it is via the mains supply or via battery and almost everything we use, is linked to electricity in one way or another. This means that there are a lot of different electrical devices about today and all of those devices have to be designed so as to provide just the right amount of current. Those people that design these devices have to understand electricity and its abilities; they have to be able to analyse an electrical circuits potential and to do this they have to use a circuit simulator. Obviously to be able to understand or in fact build a simulator, they must be trained and so simulators are not just used for designing electrical circuits, they are also used as training aides. Other times that these types of simulators are used are in industry where they may want to analyse the efficiency of some of the electrical devices that they use. Due to the increased need for methods to analyse circuits, there is now a range of software that can assist. As with many other software, today it is possible to get it not just as a download but also as an app or more recently, via cloud.
