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

Force is a physical quantity which is defined as a pull or push of a body having certain mass. Force is the factor that causes a change in the velocity of a body. Basically, a force is an external agent causes the change in the state of an object, i.e., it may move the object or may stop the movement of moving body. Force is a vector quantity. Thus, it has both magnitude and direction. Force may be classified into two broad categories namely contact force and non-contact force. Contact force is the one that acts on a body ... Read More

Electric current and Electric charge are the two most fundamental electrical quantities in any electric circuit. The major difference between current and charge is that the electric charge is the subatomic property of all the materials in nature, while the electric current is the direct flow of electric charge in an electric circuit. There are several other noticeable differences between charge and current which we are going to highlight in this article. Let's start with some basics of electric charge and electric current so that it becomes easy to understand the differences between them. What is Electric Charge? Electric charge ... Read More

Both Charge and Mass are physical properties that every matter possesses in the universe. Charge is the property of matter by virtue of which it shows electric effect. Mass is the property which gives measure of substance of a body. Also, Charge is the property that results in the electrostatic forces. On the other hand, Mass is the property that results in the gravitational forces. Both Charge and Mass are scalar quantity having magnitude only. Consequently, both are added as real numbers. In this article, we will discuss all the major differences between charge and mass by considering various parameters ... Read More

In digital electronics, the logic gates are the basic building blocks of all digital circuits that act as the switching devices and determine whether the input signal may pass through to the output of the digital circuits. As the name implies, a logic gate is a digital circuit used to perform several logical operations in a digital device or circuit. 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 ... Read More
