Nortons Theorem, like Thevenin’s Theorem, offers a technique for streamlining complex circuits. It enables us to swap out complicated circuits with much simpler equivalents that just require one resistor and one source of current or voltage. This equivalent circuit is made up of, In basic terms, Norton’s Theorem reduces a complicated network of wires, resistors, […]

With the help of Thevenin’s Theorem, we can simplify a complicated circuit with several resistors and sources into a much simpler “equivalent circuit.” The total voltage and total resistance of the original circuit are represented by a single voltage source and resistor, respectively, in this analogous circuit. In the past three tutorials, we have looked […]

An equally potent substitute for mesh current analysis is nodal voltage analysis. Matrix analysis is used in both techniques to provide effective circuit solutions. Nodal Voltage Analysis, as the name implies, uses nodal equations to represent Kirchhoff’s Current Law (KCL) and determines the voltage potentials around the circuit. The fundamental idea is that, for any […]

Mesh current analysis calculates currents in closed loops of a circuit by assigning hypothetical loop currents and using Kirchhoff’s Voltage Law. Although the basis for evaluating any electrical circuit is provided by Kirchhoffs Current Law (KCL) and Voltage Law (KVL), other methods such as Mesh Current Analysis and Nodal Voltage Analysis are also available. These […]

Kirchhoff’s Circuit Laws define voltage and current relationships and serve as the foundation for understanding complicated circuits. In one of our earlier lesson, we looked about resistors and how one equivalent resistance (RT) can represent a series, parallel, or combination of resistor connections. Ohm’s Law is readily followed by these circuits when calculating voltage and current. […]
