Electrical knowledge

This electric current takes the form of free electrons that transfer from one atom to the next. Thus, the more free electrons a material has, the better it conducts. There are three primary electrical parameters: the volt, the ampere and the ohm.

We discuss various types of electric motors including DC Motors, Induction Motors, Synchronous Motors, and other special types of motors. We explain the working principles, characteristics, uses and testing of electric motors. This category is a collection of knowledge about all things related to electric motors.

Volume I presents the basic theory of electricity and magnetism some basic DC circuits. Brush up on some basic electrical theory and deepen your knowledge about electricity. Electrical theory, part 1. In this post we cover Ohms Law, AC and DC Current, Circuits and More. What are basic electrical skills?

Is electrical engineering good? A place for electrical professionals – including electricians, electrical engineers, electronics engineers and control engineers – to help each other out. Theory, laws and formulas.

Starting with theory and advancing to Ohm’s Law, magnetism, electrical machines, AC and DC motors, inspection, maintenance, etc. EEP will present and share resources by electrical lecturers and make the free access to this resources to electrical students and all other interested in. After completion, feel free to share this quiz with your friends or co-workers and see who scores the highest. This feature is not available right now. The purpose of this Info-Tec is to help you understand the fundamentals of electrical systems.

Many problems encountered in service work are electrical problems or related to electrical problems. There are two types of electrical current in common use today: alternating current (AC), and direct current (DC). Basic electrical quantities: current, voltage, power.

This is the currently selected item. These electrical practice tests are designed in such a way to test your knowledge on wiring methods, branch circuit calculations, over current protection , motor control circuits etc. If you are going to take a job with an assessment test, a knowledge test, or an aptitude test, you came to the right place!

Two large hot wires connect to big screw terminals, called lugs, inside the service panel, providing all the power to the panel. In this section a pool of electrical topics ranging from atomic structure, ohm’s law to AC machines are covered. This section will helps in brushing up your knowledge in basic electrical concepts. I have incorporated general knowledge questions with chapter one on my quiz though for simplicity. These questions are not usually in your code book.

Resistors allow current to flow to some degree in proportion to their resistance in ohms. Except where otherwise note work provided on Autodesk Knowledge Network is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 3.
