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

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

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
