In this configuration, the input is applied at the non-inverting terminal of the op-amp. Fig. 1 Non-Inverting op-amp Configuration In this configuration, there is a … Read moreOperational Amplifier: Non-Inverting Op-Amp and Op-Amp as Buffer

Inverting Op-Amp and the Concept of Virtual Ground

Inverting Op-Amp Configuration: As discussed in the previous article, the op-amp is a very high gain differential amplifier. In the open-loop configuration, the typical gain of the op-amp is 105 to 106  Fig. Operational Amplifier Because of high open-loop gain, even for a small differential input between the two terminals, the output of the op-amp will … Read moreInverting Op-Amp and the Concept of Virtual Ground

Operational Amplifier (Op-Amp) Explained

What is the Operational Amplifier? As its name suggests, the Operational Amplifier is one type of amplifier. The basic function of any amplifier is to amplify the input signal. But apart from amplifying the signal, it is also possible to perform different arithmetic operations using op-amp. In the early days, when digital computers were not … Read moreOperational Amplifier (Op-Amp) Explained

BJT- Bipolar Junction Transistor

The invention of transistor led the invention of many other semiconductor devices including integrated circuits. And due to these integrated circuits, the modern-day computers and other electronic gadgets are possible. The bipolar junction transistor or BJT is a three-terminal semiconductor device that can act as a conductor or insulator based on the applied input signal. … Read moreBJT- Bipolar Junction Transistor

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 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 a 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 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 Figure.3, 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 within 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.
