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 ...

A Wind Turbine is a device which uses kinetic energy of blowing wind to generate electrical energy. A wind turbine consists of two or three rotor blades which are mounted on a rotor. When the blowing wind exerts a lift and drag force on these blades, the rotor starts rotating. A main shaft is attached to the rotor which is connected to an electric generator on the other end. The generator produces electricity when driven by the wind turbine. Depending on the axis of rotation, the wind turbines are classified into two types − Horizontal Axis Wind Turbine Vertical ...

A magnetic material is a type of substance or material which gets attracted towards a magnet. The magnetic material also acquires magnetization when it is placed in the magnetic field of a magnet. Depending on the magnetization property, there are two types of magnetic materials namely, Hard Magnetic Materials Soft Magnetic Materials Let's start with some basics of hard and soft magnetic materials. What is a Hard Magnetic Material? Hard magnetic materials are those types of magnetic materials that maintain a constant magnetic property after magnetization at once. Therefore, the hard magnetic materials are sometimes also termed as ... Read More
