Difference between Transformer and Amplifier
In electrical and electronics engineering, transformers and amplifiers play a crucial role in several circuits. At first sight, the function of a transformer and an amplifier may seem similar, that is, increasing the level of voltage. But, a transformer can reduce the level of voltage as well, whereas an amplifier cannot. In this article, we will discuss all the key differences between a transformer and an amplifier by considering different parameters such as basic definition, circuit components, primary function, applications, etc. But before that, let's check some of the basics of transformers and amplifiers so that it becomes easier ...
Read MoreDifference between Static Relays and Electromagnetic Relays
In electrical and electronics engineering, a Relay is an electrically operated switch which is used to connect or disconnect two circuits. Since the operation of a Relay is governed by an electric control signal, hence it can be operated automatically. Basically, the relays are designed for switching of high power circuits by using low power electric signals. Depending on the technology used, the relays can be broadly classified into two types namely Electromagnetic Relays Static or Solid-State Relays In this article, we will highlight all the key differences between an electromagnetic relay and a solid state relay ...
Read MoreDifference between Resistance and Reluctance
In electrical engineering, there are two important terms resistance and reluctance related to electromagnetic circuits such as motor, generator, transformer etc. Where, the resistance is the parameter of circuit which is regarded to electric current, whereas the reluctance is the parameter regarded to the magnetic flux in the circuit. In this article, we will highlight all the significant differences between resistance and reluctance by considering different parameters such as basic definition, unit, denotation, affected quantity, etc. Let's start with some basics of Resistance and Reluctance so that it becomes easy to understand the differences between them. What is Resistance? Resistance ...
Read MoreDifference between Relay and PLC
Both relay and PLC are devices that are used in the electrical and electronic control systems for the automation of processes. A control system that is designed by using relays is known as relay logic control (RLC). Similarly, a control system that is designed by using a microcontroller and other solid state switching devices is known as programmable logic control (PLC). In this article, we will discuss all the major differences between relay and PLC by considering different parameters such as basic definition, components, function, memory, I/O, applications, etc. But before discussing the differences, let's start with ...
Read MoreDifference between Photodiode and Phototransistor
Photodiodes and Phototransistors are both semiconductor electronic devices that convert optical energy into electrical energy. Therefore, due to their similar function, one may get confused between these two devices. Both photodiode and phototransistor sense the light from a source and generate an electric signal having the strength corresponding to intensity of the light. However, these two devices are quite different from each other in many aspects. In this article, we will highlight all the significant differences between photodiodes and phototransistors. Let's start with some basics so that it becomes easy to understand the differences between them. The one most ...
Read MoreDifference between Petrol Engine and Diesel Engine
A machine which consists of moving parts and converts one or more form of energy into mechanical energy (usually in the form of motion) is known as an engine. Depending on the fuel used as the source of energy, the engine may be classified in following the types − Steam engine Diesel engine Petrol engine, etc. In this article, we will discuss all the major differences between petrol engine and diesel engine by considering different parameters such as working principle, fuel-air mixing, ignition, power, applications, etc. But, before discussing the differences, we will learn the basics of ...
Read MoreDifference between Permeance and Reluctance
In electromagnetism, permeance and reluctance are the two major quantities related to magnetic circuits. Both permeance and reluctance provide information about the ease and opposition in the flow of magnetic flux offered by the core material of the magnetic circuit. Where, the reluctance is the measure of opposition in the flow of magnetic flux while the permeance is the measure of ease offered by the core material in the flow of magnetic flux. In this article, we will highlight all the key differences between permeance and reluctance. Let's start with some basic information about Permeance and Reluctance so that it ...
Read MoreDifference between Linear Variable and Rotary Variable Differential Transformers (LVDT vs RVDT)
LVDT and RVDT are types of passive transducers that convert displacement into an electric signal. Both LVDT and RVDT are types of inductive transducers and their construction is just like a transformer. In this article, we will highlight all the differences between LVDT and RVDT. Let's start with some basics so that it becomes easier to understand the differences between them. What is an LVDT? LVDT stands for Linear Variable Differential Transformer. It is a passive inductive transducer that converts linear displacement into electrical signal for measurement purposes. A typical LVDT consists of a primary winding, two secondary windings ...
Read MoreDifference between LED and Photodiode
LED and Photodiode are both semiconductor-based electronic devices that function by the interaction of light energy and electricity. LED converts the electricity into light, whereas a photodiode converts the light energy into electricity. Therefore, LEDs and photodiodes are quite different in the way they operate. In this article, we will highlight all the major differences between LEDs and photodiodes. Let's start with some basics first so that it becomes easy to understand the differences between them. What is an LED? LED stands for Light Emitting Diode. An LED is basically a PN junction semiconductor diode which emits light when ...
Read MoreDifference between Induction Motor and Transformer
Both transformers and induction motor both are the most extensively used electrical machines in practice. The transformer is an electromagnetic static machine while the induction motor is an electromechanical energy conversion device. Since the induction motor and transformer are functionally quite similar because both work on the Faraday’s law of electromagnetic induction, therefore it is required to understand the differences between them. In this article, we will highlight all the significant differences between an induction motor and a transformer. Let's start with some basics first so that it becomes easier to understand the differences between them. What is an ...
