Electrical Circuit Analysis in Electrical Engineering
The electrical circuit analysis is a set of techniques used for quantitative analysis of a circuit.
Purpose of Circuit Analysis:
The circuit analysis helps the engineers to find out the behavior of each element in the circuit. It analyzes the circuit before physically connecting it. Using pen and paper for electrical circuit drawing and calculation. This can save a lot of money and avoid a hazardous situation like a short circuit and component loss.
Elements of Circuit:
In electrical engineering, an electrical circuit is a closed loop that can pass the current from source to load. A circuit may have at least one or more than one load that absorbs power. Load elements of the circuit are passive elements. Where active elements provide power to the passive components.
Types of Analysis:
Circuit analyses are transient analysis and steady-state analysis. In the case of transient circuit analysts, the circuit is analyzed at the time of powering the circuit. In steady-state circuit analysis, the power source is considered Direct Current (DC).
Gustav Kirchhoff was a German physicist, who presented two laws; Kirchhoff’s Current Law (KCL) and Kirchhoff’s Voltage Law (KVL). Ohm law is a very basic one, which may not be sufficient to analyze a complex circuit.
Mesh current Analysis provide a procedure for electric circuit analysis using mesh current as the circuit variable. The mesh analysis makes use of Kirchhoff’s Voltage Law as a basic key to analyze the circuit.
