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 ...

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 More

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 ...

There are two physical quantities namely Permittivity and Permeability that play a vital role in the field electrical engineering. Permittivity is related to electrostatics and it is the measure of electrical polarization of a dielectric material when it is placed in an external electric field. Permeability is related to electromagnetism and it is the measure of magnetic polarization of a magnetic material when it is placed in an external magnetic field. In this article, we will highlight all the key differences between permittivity and permeability by considering different parameters like basic definition, unit, formula, importance, etc. Let's start ...

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 More

In digital electronics, logic gates are the basic building blocks of all digital circuits that act as the switching devices in the digital circuits. Therefore, a logic gate is a digital circuit used to perform several logical operations in a digital device or system. A logic gate can accept one or multiple inputs but produces only a single output. Where, the output of a logic gate is determined by the combination of input signals. The operation of the logic gates is based on the Boolean algebra. These days, logic gates are being used in every digital electronic device such as ... Read More

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 ...

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 More

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 ... Read More

Heating is a process of increasing the temperature of a body at an acceptable level by using thermal energy. The mechanism involved in heating is generally referred as a heating system. When the process of heating is performed by using the electric current, i.e. the electric current is converted into heat energy by employing a suitable mechanism is called the electric heating. The principle behind the electric heating is the heating effect of electric current which states that when an electric current flows through a conducting medium, the medium resists the flow of this current which results in the rise ...
