The human eye has six and seven million cone cells, each of which contains one of three different types of opsins, which are proteins that are sensitive to color. When photons of light strike these opsins, they transform, setting off a cascade that produces electrical signals, which then send the messages to the brain so that they can be interpreted.Making a machine that can read this on a level that is understandable to humans has always been a difficult task because the process as a whole is so complicated. Emulating human vision in terms of recognizing patterns and faces, as ... Read More
A JavaScript constructor is a function that creates and initializes an object instance of a class. A constructor is used to create a new object and set values for existing object properties. The Error() constructor in JavaScript is used to create new error objects. Error objects are thrown when runtime errors occur. The Error object can also be used as a base object for user-defined exceptions. See below for standard built-in error types.SyntaxFollowing is the syntax for an Error( ) constructor −new Error() new Error(message) new Error(message, options) new Error(message, fileName) new Error(message, fileName, lineNumber)The Error() constructor can be defined ...

In this tutorial, we are going to learn how to replace all the line breaks in JavaScript code using a tag. There are various methods using which we can replace all the line breaks with tag. Some of the methods are given below −Using String replace() Method and RegExIn this method we are using the String.replace() method to replace all the line breaks in the plain text with the tag. Here the RegEx refers to the regular expression that we write inside the string.replace() method.SyntaxFollowing is the syntax to use replace() method −sentence.replace(/(?:\r|\r|)/g, "");Here sentence is the string ...

Electrical power is produced at the generating stations which is then transported to the points of utilization with the help of electric power lines. The electric utility companies install two different types of electric power lines viz. transmission line and distribution line for conveying the electric power from power plant to consumer’s premises for utilization.This article is meant for describing the key differences between transmission line and distribution line. We also briefly explained that what the transmission line and distribution line are.What is a Transmission Line?Transmission lines are the power lines that carry the electric power at high voltage from ...

An electric power plant, also called generating station, is a setup that is used for generating electrical power. A power plant consists of a number of alternators (AC generators) which are driven by the prime movers such as IC engines, steam turbine, gas turbine, etc.The energy from some source such as steam, water, burning of fossil fuels, nuclear reaction, etc. is given to the prime mover, it starts rotating, and in turn rotate the alternator to which it is coupled. The alternator coverts this mechanical energy of rotation of turbine into electrical energy, which is then transmitted for the utilization.Based ... Read More

Electricity is nothing but a form of energy. The electricity is caused by the electric charge, where the charge is a property of subatomic particles such as electrons and protons. The electrons carry negative charge while the protons carry a positive charge.Technically, electricity is the phenomenon which involves either accumulation or movement of electric charge. Therefore, based on these two parameters (accumulation and movement of charge), the electricity can be of two types viz.Static ElectricityCurrent ElectricityIn this post, we will highlight all the significant differences between static electricity and current electricity by considering various factors such as basic definition, cause, ...

A Power Plant is a setup of various equipment which are connected together to produce electricity. However, there are many technologies evolving day by day to produce electricity, two of them that produces electricity from solar power are solar power plant and solar thermal power plant. A solar power plant is also called a solar photovoltaic power plant.In this article, we will describe the differences between "solar power plant" and "solar thermal power plant". But, before highlighting their differences, we will see what a solar power plant and a solar thermal power plant are.What is a Solar Power Plant?An arrangement ... Read More
In AC electrical wiring, three types of conductors are used viz. phase wire, neutral wire and earth or ground wire. The phase wire is the live wire of the system which carries electric current from source to load. But, sometimes there is a confusion between neutral and earth wire because both of the conductors are considered to operate with zero voltage or lower voltage than phase wire voltage.Therefore, this article is created for explaining the differences between neutral and earth wire. But, it may difficult to understand the differences between neutral wire and earth in the beginning, so we have ... Read More
A closed path followed by electric current is known as electric circuit. Based on the type of electric supply, the electric circuits can be classified into two major types viz. DC circuit and AC circuit.Every electric circuit consists of a number of circuit elements such as energy sources, resistors, inductors, capacitors, etc. In a DC circuit only resistors are meaningful, because the inductor and capacitor are the frequency dependent elements and for DC supply the frequency is zero. On the other hand, all the three elements, i.e. resistors, inductors and capacitors are functional in an AC circuit.Based on the combination ... Read More
