Difference between Induction Heating and Resistance Heating
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 ...

Read MoreDifference between Horizontal Axis and Vertical Axis Wind Turbines
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 ...
Read MoreDifference between Hard Magnetic Material and Soft Magnetic Material
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 MoreDifference between Gravitational Force and Electrostatic Force
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 MoreDifference between Electric Current and Electric Charge
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 MoreDifference between Charge and Mass
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 MoreWhat is a Doubly-Excited System?
A doubly-excited system is the type of magnetic system in which two independent coils are used to produce magnetic field. Examples of doubly-excited systems are synchronous machine, separately excited DC machines, loudspeakers, tachometers etc.Consider a doubly-excited system as shown in the figure, it consists of a stator wound with a coil having a resistance of R1 and a rotor wound with a coil of resistance R2. Both the coils are excited by independent voltage sources.Following assumptions are made to analyse a doubly excited system −For any rotor position the relationship between flux-linkage (ψ) and current is linear.Hysteresis and eddy current ...

This tutorial explains how to clear an entire spreadsheet and a specified range in MS Excel using two simple methods Method 1: How to Clear The Entire Sheet? This is an easy procedure. If you want to clear the entire sheet, you can use a keyboard shortcut or from the corner cell. We learn how to do ...
Read MoreHow to Check The Size of Each Worksheet of a Workbook?
It is commonly known that when you right-click on an Excel file, you can see its properties and size. But what about when you want to know the size of individual worksheets within the file? Accountants and data analysts maintain large Excel workbooks with multiple worksheets. Understanding the file size can help determine the best way to analyze it. Some might want to begin with the heavy worksheet, or some may start with the lighter one. It often turns out that one sheet takes up the majority of the space in the workbook. This tutorial explains how to identify the ...
