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).

Thevenin Equivalent Circuit

According to Thevenin Theorem, a complex circuit is reduced to two resistor network, Thevenin Resistor, and Load resistor and a Thevenin Voltage source to avoid redundant computation to analyze a frequent changing resistor.

Online Parallel Resistors Calculator: Add Parallel Resistors in Circuit

August 5, 2024May 27, 2018 by Gul Faraz

Resistors are said to be parallel if there is only one path for the flow of current. The total resistance in parallel is less than the individual resistors in parallel.

Resistors in sereis

Resistors are in series if there is only one path for the flow of current. That’s why current remain same for all the resistors in series.

Kirchhoff's voltage law KVL Infographics

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.
