Difference between Primary Distribution and Secondary Distribution Systems
Introduction to Electricity Distribution Electricity distribution refers to the process of distributing the electrical power from generating stations to the consumers. In the first step, electricity is distributed to substations from the generating stations through transmission lines by increasing the voltage level to reduce transmission losses. In the second step, the increased level of voltage is stepped down using the transformers and supplied to consumers by the utility companies. In any industry, more than one voltage level is used for different purposes like 415 V, 690 V, 6.6 kV, and 11 kV. There is a process of voltage conversion ...
Read MoreDifference between Pipe Earthing and Plate Earthing
In electrical power system, electrical earthing is one of the most important concept used to provide safety and protection to both human and equipment. Electrical earthing, also called as grounding, is basically a path of very low-resistance between the electrical equipment/system and the earth surface. The main purpose of electrical earthing in an electrical system is to provide a safe path for leakage electric current to flow into the earth’s conductive surface to reduce the risk of electrical accidents. Therefore, electrical earthing is an efficient and reliable way of protecting electrical equipment, individuals, and premises against electrical faults ...
Read MoreDifference between Step-Index Fiber and Graded-Index Fiber
Optical fiber technology is defined as technology that is capable to transmit information in the form of light pulses with the help of a high-quality glass or plastic material. It looks like a transparent filament. In this article, we will go through optical fiber, its types, and the differences between them. So, let's begin with the definition of optical fiber. What is an Optical Fiber? Optical fiber is thin a thin or flexible glass or plastic material used to transmit information in the form of light. Glass or plastic serves as a medium to allow the passage of ...
Read MoreDifference between Hybrid Electric Vehicle and Electric Vehicle
The automotive industry is undergoing a major revolution in the method we power our vehicle. The hybrid electric vehicle (HEV) and electric vehicle (EV) are at the leading position of this revolution. The fundamental difference between hybrid electric vehicle and electric vehicle is that electric vehicle relies only on electric batteries as energy source, while hybrid electric vehicle uses both fuel and electricity as the energy source. In this article, we will explore the other major differences between hybrid electric vehicle and electric vehicle. But before that let’s briefly get their overview individually. What is a ...
Read MoreBipolar-Output D/A Converters
In digital electronics, a D/A converter, also called Digital-to-Analog Converter, is an electronic device that converts digital signal inputs into analog signal outputs. Depending on the polarity of output signals, D/A converters can be classified into two types namely, Unipolar-Output D/A Converters and Bipolar-Output D/A Converters. A unipolar-output D/A converter can produce only positive analog signals as output, whereas a bipolar-output D/A converter can produce both positive and negative analog signals as output. In this tutorial, we will discuss bipolar-output D/A converts, along with their construction, types, working, advantages, and applications. So, let’s start with the basic definition ...
Read MoreBlock Coding in Digital Electronics
In digital electronics, block coding is a technique of encoding data into a specific format. It is mainly used to detect and correct errors occurred in the information during transmission and storage. This is done by adding a block code of redundant information to the main data. Block coding is mainly employed to create a robust method of data transmission and storage. In the block coding, data is encoded by splitting it into multiple blocks of a fixed size and applying encoding techniques to each of these blocks separately. In block coding, the input data is taken ...
Read MoreDifference between Ammeter and Voltmeter
Both Ammeter and Voltmeter are electrical measuring instruments used for measuring the current and voltage in an electrical circuit, respectively. Read through this article to find out more about Ammeter and Voltmeter and how they are different from each other. Before getting into the differences between Ammeters and Voltmeters, let's get some basic information about these two devices. What is an Ammeter? An electrical measuring instrument that is used to measure electric current in an electric circuit is known as ammeter. As the measurement unit of electric current is ampere and this instrument is used to measure the ...
Read MoreDifference between HDMI and USB
HDMI and USB are two popular interfaces used for connecting devices and peripherals with computers and other electronic devices. The fundamental difference between HDMI and USB is that USB (Universal Serial Bus) is an interface designed for data transfer, while HDMI (High-Definition Multimedia Interface) is designed for transferring high-quality audio and video signals. In this article, we will discuss the important differences between HDMI and USB. But before discussing the differences, let us first get an overview of HDMI and USB individually. What is HDMI? HDMI is an acronym for High-Definition Multimedia Interface. HDMI is a digital interface designed to transfer high-quality ...
Read MoreDifference between Resistance and Reactance
Resistance and reactance are the two major parameters of an electric circuit element that together form the impedance of the circuit element. One most significant difference between resistance and reactance is that the resistance is the opposition in the flow of electric current offered by a circuit element called resistor, whereas the reactance is the opposition in the change in the magnitude and direction of the current and voltage offered by a circuit element called inductor or capacitor. The combined opposition offered by the resistance and reactance in an electric circuit is known as impedance of the circuit. In this ...
Read MoreDifference between Open Circuit and Short Circuit
A closed path following an electric current is known as an electric circuit or simply circuit. An electric circuit consists of a number of circuit components such as resistors, inductors, capacitors, etc. Sometimes in an electric circuit, two undesirable conditions occur namely open circuit and short circuit. Basically, these two states of an electric circuit are considered as faults in the circuit and hence are undesirable. In this article, we will highlight the major differences between an open circuit and a short circuit. What is an Open Circuit? As its name suggests, an open is a break ...
