Resistors in Series and Parallel

In this tutorial, it has been explained that when the bunch of Resistors is connected either in a Series or Parallel then how to find the equivalent resistance. Resistors in Series As shown above, when the n- resistors are connected in series connection, then the total resistance will be the summation of individual resistance. Proof … Read moreResistors in Series and Parallel

Loop, Mesh, Node and Branch Explained

What is Branch?

A branch represents the single circuit elements like resistor, capacitor, inductor, voltage or current source.

                                                                  Figure. 1

For example, for the circuit shown in the figure 1, there are five branches. A 10 V voltage source, 2A current source, 4 Ω, 5 Ω and 3 Ω resistors.

What is Node ?

A node is the point in the circuit where two or more circuit elements (or branches) are connected.                               Figure. 2 ( Representation of Four Nodes in the Circuit)

For example, as shown in Figure 2, the above circuit contains the Four nodes. The node A, B, C and D.

What is Loop ?

Any closed path in the circuit is called as a loop.

A loop is a closed path formed by starting at a node, passing through a
set of nodes, and returning to the starting node without passing through
any node more than once.

Figure. 3 (Representation of Loop in the Circuit)

For example, as shown in the Figure.3, the circuit contains three loops.

The first is loop A-B-D-A, the second loop is B-C-D-B. And the third loop is A-B-C-D-A.

What is Mesh?

A mesh is a closed path in the circuit, which does not contain any other close path inside it.

For example, as shown in the Figure.3, the loop 1(A-B-D-A) and loop 2 (B-C-D-B) does not contain any other closed path within them. And they are the example of the Mesh.While loop 3 (A-B-C-D-A) contains loop 1 and loop 2 with in it. So, it can’t be called as a Mesh.

Note: All  Mesh are loops but not all the loops are Mesh.

What is Multivibrator? Astable, Monostable and Bistable Multivibrator Explained.

What is Multivibrator? The Multivibrator circuits are widely used in electronics. It is the electronics circuit which is used to implement the two state devices like Relaxation Oscillator, Timer and Flip-flops. Here the two states refers to the two voltage levels of the output. (e.g  0V, and 5V). Many times the two voltage levels are … Read moreWhat is Multivibrator? Astable, Monostable and Bistable Multivibrator Explained.
