The fundamental unit of electricity is the negative charge of the electron or the positive charge of an ionised atom that has lost a single electron resulting from the positive charge on the protons in the nucleus outnumbering that of the remaining electrons.

Electrical charge is measured in coulombs symbol C. The charge on a proton is approximately 1. An electrical current is a flow of electric charge, measured in amperes symbol A , where a current of one ampere is a total charge of one coulomb flowing in one second. Ampere is often abbreviated to amp. This course will use conventional current flow, the predominant convention in the electronics industry, which is indicated in the direction taken by positive charges.

In metal wires, the current is carried by electrons, which move in the opposite direction. This was not known at the time the convention was established. A quantity closely related to current is voltage.

Voltage is a measure of the potential difference between two points. A potential difference of one volt symbol V will drive a coulomb of charge through a resistance of one ohm every second. Note that we usually refer to current flowing through a component such as a resistor, but to the voltage being across the component because two points are required to define the voltage.

If you are interested in learning everything about electricity, you should start by understanding the basic components that make up any electrical design and how they work. Think about how the great pyramids of Egypt were built using just blocks of rock. The rocks themselves were nothing, but when combined with a careful design they formed such grand structures! Similarly, you need to know about the basic electrical components and how they work together to create wonderful modern electrical systems.

Any university b. Also, We have provided B. Also, check the below links for more information:. With the help of this subject, the students will learn the fundamentals of Electrical engineering and Electronic engineering. Also, they will go to experience the Practical implementation of fundamental theory concepts along with the learning process of different applications of generally used electrical machinery.

Нет, конечно. Я просто подумал… - Толстяк быстро убрал бумажник.  - Я… я… - Совсем растерявшись, он сел на край постели и сжал руки. Кровать застонала под его весом.  - Простите.

Эти числа отлично работают при создании шифров, потому что компьютеры не могут угадать их с помощью обычного числового дерева.
