Electric power definition The electric power P is equal to the energy consumption E divided by the consumption time t: P is the electric power in watt (W). E is the energy consumption in joule (J). t is the time in seconds (s). Example Find the electric power of an electrical circuit that consumes 120… Continue reading Electric Power

Electrical Resistance
Resistance definition Resistance is an electrical quantity that measures how the device or material reduces the electric current flow through it. The resistance is measured in units of ohms (Ω). If we make an analogy to water flow in pipes, the resistance is bigger when the pipe is thinner, so the water flow is decreased. Resistance calculation The resistance… Continue reading Electrical Resistance
Electric Current
Electric current definition Electrical current is the flow rate of electric charge in electric field, usually in electrical circuit. Using water pipe analogy, we can visualize the electrical current as water current that flows in a pipe. The electrical current is measured in ampere (amp) unit. Electric current calculation Electrical current is measured by the rate of… Continue reading Electric Current
Electrical Voltage
Electrical voltage is defined as electric potential difference between two points of an electric field. Using water pipe analogy, we can visualize the voltage as height difference that makes the water flow down. V = φ2 – φ1 V is the voltage between point 2 and 1 in volts (V). φ2 is the electric potential at point #2 in volts… Continue reading Electrical Voltage
Problem
We assure you that you will not find any problem with our Dart tutorial. But, if you find any mistake, you can post it in our comment section.
Key Points to Remember
Before learning the Dart, we should keep these concepts in mind. These concepts are given below. Everything in Dart is treated as an object including, numbers, Boolean, function, etc. like Python. All objects inherit from the Object class. Dart tools can report two types of problems while coding, warnings and errors. Warnings are the indication… Continue reading Key Points to Remember
Why Dart?
We define the characteristics of Dart in the following point. Dart is a platform-independent language and supports all operating systems such as Windows, Mac, Linux, etc. It is an open-source language, which means it available free for everyone. It comes with a BSD license and recognized by the ECMA standard. It is an object-oriented programming… Continue reading Why Dart?
History
Dart was revealed for the first time in the GOTO conference in the month of 10th – 12th October 2011 at Aarhus, Denmark. It is initially designed by the Lars bark and Kespar and developed by Google. The first version 1.0 of Dart was released on November 14th, 2013, intended as a replacement of JavaScript. In July 2014, the first… Continue reading History
What is Dart?
Dart is a general-purpose, high-level modern programming language which is originally developed by Google. It is the new programming language which is emerged in 2011, but its stable version was released in June 2017. Dart is not so popular at that time, but It gains popularity when it is used by the Flutter. Dart is… Continue reading What is Dart?
Online Dart Editor
We have discussed Dark installation on the various operating systems so far, but if we do not want to install Dart then there is an online Dark editor (Known as DartPad) is available to run the Dark programs. The online DartPad is provided at https://dartpad.dev/. The DartPad offers to execute the dart scripts and display HTML and also… Continue reading Online Dart Editor
