Analîzê Tiranê ya Zênkariyan an Analîzê Circûitê

Network Analysis is a process by which we can calculate different electrical parameters of a circuit element connected in an electrical network. An electrical circuit or network can be complicated too and in a complicated network, we have to apply different methods to simplify the network for determining the electrical parameters. The circuit elements in a network can be connected in different manners, some of them are in series and some of them in parallel. The circuit elements are resistors, capacitors, inductors, voltage sources, current sources etc. Current, voltage, resistance, impedance, reactance, inductance, capacitance, frequency, electric power, electrical energy etc are the different electrical parameters we determine by network analysis. In short, we can say, an electrical network is the combination of different circuit elements and the network analysis or circuit analysis is the technique to determine the different electrical parameters of those circuit elements.

Graph of an Electrical Network

When we replace all the circuit elements of an electrical network by hand-drawn lines, then the figure is known as the graph of the network. The figure – 2 below shows the graph of the above network in figure – 1.

The line represents the circuit element is called the branch of a network. The point where two or more branches meet is called node of the network. The direction of current through the element is represented by arrowhead drawn on the branch. The direction of the current in a graph can be considered arbitrarily. When we draw a graph of a network with the direction of current (the direction may
