EE07: DC MOTOR STARTING CURRENT, BACK EMF, ARMATURE CURRENT AT SPECIFIC SPEED CALCULATOR

SOURCE VOLTAGE:V

ARMATURE RESISTANCE:ohm

MOTOR SPEED CONSTANT:V/rpm     If you don’t know, you can find this. You need to divide voltage generated to speed at that voltage.

MOTOR SPEED: rpm


RESULTS

STARTING CURRENT: A

BACK EMF: V

ARMATURE CURRENT RUNNING AT :A

TEA BREAK WITH C++: INSTALLING IDE

NOTE: You may download codes and extra source material for this book from https://bookofengineering.com/easyseries/

Installing IDE

For all the programming languages the beginning is the printing “Hello World” sentence. So, this is some kind of tradition. But before doing that we need to have the C++ IDE. IDE stands for Integrated Development Environment. So basically, the place where you will communicate with the PC. So, the “language” is coming here. So, for different programming languages there are different environments so that you can talk to your PC and instruct it.

TEA BREAK WITH C++ EASILY WITH THIS EASY BOOK

NOTE: You may download codes and extra source material for this book from https://bookofengineering.com/easyseries/

With this EASY book, I aimed to give the basic programming info as fast as possible without giving so much detail and making you feel bored. Comparing to the other programming books, in this book you will get the essence of the subject, without entering into lots of “unnecessary” details which you may not need to learn at the beginning of learning this language. Especially simple examples are used to show the functions of the codes introduced. I intentionally, tried to keep the text as short as possible so that you can start programming with C++ faster and have time to try it yourself. So this is a great book who wants to start programming as soon as possible and get the idea easily without diving into details.

LEARNING GITHUB

Github is a place where people collaborate to code. You can add people to projects. You can “fork” from other people’s work. You can collaborate with anyone around the world. Version controlling lets you differentiate between different versions. Do you remember giving your code file that you give names like final.cpp, finalfinal.cpp, final2.cpp, thisislast.cpp and goes on. This is the same thing, online.

EE99 – CAPACITOR VALUE READING TABLE

Capacitor manufacturers generally give the value of capacitor on capacitor but, in some cases there may be not enough space. In that case, they use simple notation. If it is 2 digits number then no issues. You can say the value seen is the value on capacitor. But if it has 3 digits then the first two digit you take as is and remaining last digit is the number of zeros following that first two digits. See table below;
