After all, it’s all about basic electric circuits elements such as branches, nodes, and loops. EEP – Electrical Engineering Portal » Electric Circuits? Share with your Facebook friends! Since the elements of an electric circuit can be interconnected in several ways, we need to understand some basic concepts of network topology.
To differentiate between a circuit and a network, we may regard a network as an interconnection of elements or devices, whereas a circuit is a network providing one or more closed paths. We do this even though the word network and circuit mean the same thing when used in this context. It’s all about circuit elements such as branches, nodes, and loops. A branch represents a single element such as a voltage source or a resistor.
In other words, a branch represents any two-terminal element. The circuit in Figure 1 has five branches, namely, the 10V voltage source, the 2A current source, and the three resistors. We demonstrate that the circuit in Fig. 1 has only three nodes by redrawing the circuit in Fig. The two circuits in Figs.
A loop is said to be independent if it contains at least one branch which is not a part of any other independent loop. Independent loops or paths result in independent sets of equations. It is possible to form an independent set of loops where one of the loops does not contain such a branch. The third loop could be the one with the 2Ω resistor in parallel with the 3Ω resistor. This does form an independent set of loops. As the next two definitions show, circuit topology is of great value to the study of voltages and currents in an electric circuit. For example, two elements are in series if they share one common node and no other element is connected to that common node.
In the circuit shown in Fig. 1, the voltage source and the 5Ω resistor are in series because the same current will flow through them. The 2Ω resistor, the 3Ω resistor, and the current source are in parallel because they are connected to the same two nodes b and c and consequently have the same voltage across them. The 5Ω and 2Ω resistors are neither in series nor in parallel with each other. Fundamentals of Electric Circuits by Charles K. Click here to cancel reply.
