Updated on 22-Sep-2022 07:38:47
A servo motor is a special type of electric motor which is used as a rotary or linear actuator for precise control of angular or linear position, velocity, acceleration and many other closed-loop position control applications. Servo motors are designed with long rotor length and small diameter. Thus, due to low inertia, the servo motors have a high speed response. A typical servo motor consists of a motor, feedback system, controller, etc. Where, it uses the position feedback to control the speed and final position of the motor. The servo motor is equipped with an encoder or a speed sensor ... Read More

Difference between Voltage Amplifier and Power Amplifier

An amplifier is an electronic circuit that is used to increase the strength of a signal in terms of voltage, current, power, etc. It accepts a weak signal at the input terminal and produces a raised signal at the output, though the output signal is identical to the input signal. The function that an amplifier performs is known as amplification. The amount of amplification performed by the amplifier is determined by a factor known as gain of the amplifier. Depending on the applied input signal and generated output signal, the amplifiers are broadly classified into two major types namely, ... Read More

Wires are the most fundamental components of an electrical and electronic system that convey electricity from one point to another. In practice, we use two major types of wires for power transmission namely solid wire and stranded wire. In this article, we will consider various parameters to understand the major differences between a solid wire and a stranded wire. But before that, let's start with some basics of solid wire and stranded wire so that it becomes easier to understand the differences between them. What is a Solid Wire? A solid wire is the type of conductor wire that ... Read More

Difference between Positive and Negative Feedback in a Control System

In a control system, the process of sampling and returning the output (or a part of output) to the input end of the system is known as feedback. The feedback is used to improve the operating performance to obtain the desired output from a control system. The feedback signal may be a voltage or a current depending on the operation of the feedback sampling system. It must remember that the feedback is a unidirectional process, i.e. the sampled feedback signal always flows from output to input side. The use of feedback in a system makes it a closed loop control ... Read More

Both PLC and DCS are extensively used in industrial automation to control and automate a machine or a process. Both PLC and DCS monitor the input and field signals and take the decisions based on how they are programmed. There are many differences between PLC and DCS which we will highlight in this article. Let's start with some basics of PLC and DCS so that it becomes easier to understand the differences between them. What is a PLC? PLC stands for Programmable Logic Controller. The PLC is a microcontroller device that is used to control and automate a machine ... Read More

Difference between Overhead Lines and Underground Cables

Electrical power is produced at the power generating plants which are located far away from the load centers. Therefore, we need to transport the electrical power generated at the power generating plant to the points of utilization or load points. For this purpose, two major systems of conductors are developed called transmission system and distribution system. Both transmission and distribution systems are further classified into two types namely, Overhead system Underground system In the overhead system of transmission and distribution, the overhead line wires supported by poles are used for power transportation; while in the underground system, insulated ...

Difference between Ordinary Light and LASER Light

Manish Kumar Saini
Updated on 02-Sep-2022 08:29:04
Ordinary light and LASER light are both forms of electromagnetic waves, hence they can travel at the same speed, i.e., speed of light, in vacuum. However, there are several differences between an ordinary light and LASER light. One major difference is that the ordinary light has a mixture different wavelength whereas the LASER light is monochromatic, i.e. has only one wavelength. Other differences between ordinary light and LASER light are listed in the table given below. What is Ordinary Light? An ordinary light is the type of electromagnetic radiation having many wavelengths and is incoherent light. As the ordinary ... Read More

Several types of devices are used to emit light. The two special devices that are used as the source of light in flashlights, traffic signals, medical instruments, etc. are LED and LASER. Both LED and LASER can emit electromagnetic radiation in the form of light. Although, these are different from each other. In this article, we will highlight all the major differences between LED and LASER. Let's start with some basic information about LED and LASER so that it becomes easy to understand the differences between them. What is LED? LED stands Light Emitting Diode. The LED is a ...

Difference between kW and kVA

Manish Kumar Saini
Updated on 02-Sep-2022 08:11:39
In any electric circuit (AC or DC), the electric power is one of the major electrical quantity. The electrical power is broadly classified into three types namely active power, reactive power and apparent power. These three types of electric powers are measured in different units. Where, the active power is measured in Watts (W), the reactive power is measured in Volt Ampere Reactive (VAR) and the apparent power is measured in Volt Ampere (VA). But in practice, these powers are measured in larger units, i.e., kW (kilo-Watt), kVAR (kilo Volt Ampere Reactive), and kVA (kilo Volt Ampere). Read through this ... Read More

Difference between Inverting and Non-Inverting Amplifier

Manish Kumar Saini
Updated on 02-Sep-2022 08:21:33
In electronic circuits, we use an electronic device called operational amplifier (Op-Amp). The operational amplifier is a high-gain multistage differential amplifier. It has two inputs and one output, where the input terminals are named as inverting terminal and non-inverting terminal. The inverting terminal of the Op-Amp is marked with positive (+) polarity, whereas the noninverting represents the negative (-) polarity terminal. Depending on the circuit configuration, the operational amplifier is classified into two types namely, Inverting Amplifier Non-Inverting Amplifier This article is meant for explaining the differences between an inverting amplifier and a noninverting amplifier. But before that, ... Read More
