Difference 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 MoreDifference between Amplifier and Oscillator
In electronics and communication engineering, amplifiers and oscillators are two important circuits. The major difference between an amplifier and an oscillator is that an amplifier increases the magnitude of a signal, while an oscillator generates an oscillating signal. However, there are many more differences between an amplifier and an oscillator that we shall learn in this article. But, before highlighting the differences, let's get a brief overview of what amplifiers and oscillators are. What is an Amplifier? An amplifier is an electronic circuit which accepts a weak signal as its input and produces an output signal of high magnitude or ...
Read MoreDifference between Yield and Return in Python?
In Python, the definition of generators is accomplished with the help of the yield statement. Therefore, before we dive into the specifics of what yield actually does, it's important that you get an overview of generators. If you have exposure to Python, then there is a good probability that you have previously worked with Python generators. Generators play an important function in Python. In Python, iterators can be generated using generators, however this process takes a somewhat different form. Python Generators are functions that may be dynamically paused and resumed and create a succession of outcomes. They can also be ...
Read MoreDifference between Voltage Amplifier and Power Amplifier
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 MoreDifference between Solid and Stranded Wire
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 MoreDifference between Positive and Negative Feedback in a Control System
In a control system, the process of sampling and returning the output (or a part of output) to the input end of the system is known as feedback. The feedback is used to improve the operating performance to obtain the desired output from a control system. The feedback signal may be a voltage or a current depending on the operation of the feedback sampling system. It must remember that the feedback is a unidirectional process, i.e. the sampled feedback signal always flows from output to input side. The use of feedback in a system makes it a closed loop control ...
