The sign convention for passive components is an arbitrary but widely accepted rule that says, Point the current arrow into the positive voltage terminal of an element. This article is based on conventional current direction, not electron current direction.

For every element in a network you can define a a current and a voltage. If voltage and and current point the same direction, it's called "receptor". If they are in opposite direction its' called "generator". The most common convention is to use "receptor" for resistors, capacitors and inductors and "generator for sources".

It would be simple—a little too simple at this point—if we could instantly write down the one equation that relates these two voltages. Until we have more knowledge about how circuits work, we must write a set of equations that allow us to find all the voltages and currents that can be defined for every circuit element.

In electrical engineering, the passive sign convention ( PSC) is a sign convention or arbitrary standard rule adopted universally by the electrical engineering community for defining the sign of electric power in an electric circuit. The convention defines electric power flowing out of the circuit into an electrical component as positive, and power ...

Kirchoff’s laws state two relatively intuitive facts: 1. The voltage at a given point in a circuit is uniquely defined. From this simple statement follow two important rules: i. If there are two (or more) paths to go from a point A in a circuit to a point B, the voltage drop along each of those paths is the same. ii.

Kirchhoff's current law and Kirchhoff's voltage law are the basis for analysis of lumped parameter circuits. These laws, together with the voltage-current characteristics of the circuit elements in the system, provide us with the ability to perform a systematic analysis of any electrical network.

Voltage, electric potential difference, electromotive force emf, electric pressure or electric tension is the difference in electric potential between two points, which (in a static electric field) is defined as the work needed per unit of charge to move a test charge between the two points. In the International System of Units, the derived ...

Use solved node voltages to solve for the desired circuit entity. The above algorithm is very basic and useful for 2 x 2 and 3 x 3 size matrices. Generally as the number of major node voltages increase and the order of the matrix exceeds 3, numerical methods (beyond the scope of this course) are employed, sometimes with the aid of computers, to solve such circuit networks.

An electric circuit is an interconnection of electrical elements.A circuit consists of a mesh of loops reepresented as branches and nodes in an undirected graph.Circuit components reside in the branches .Connectivity resides in the nodes.Nodes represent wires.Wires represent equipotentials. 1.
