Electric current is the ordered movement of charged particles

[zihadhosenjm40]

If you smell something burning while driving, stop immediately, remove the terminals from the battery and call a tow truck, as further movement can be life-threatening. These are all basic rules that even a humanities student can handle, but if you are confused by any phenomenon, it is better to consult an auto electrician.

Autoelectrics Basics. Part 1. Basic Laws
Hi all!

When diagnosing a car, many people start to have questions paytm data the electrical part. Unfortunately, not everyone was imbued with the basic laws of electrodynamics in school, college or university, which led to gaps in the material part. Moreover, few have comprehended the delights of amateur radio, which expands knowledge in the field of electronics. Therefore, I decided to start a series dedicated to auto electrics (and electrics in general) to help those who walked during lectures with girls and swallowed every day of youth, and now suffer in the garage.

So where should you start?

I think, from the basic laws of electrical engineering, namely:
1. Basic concepts
2. Current, voltage, resistance
3. Ohm's law for a section of a circuit
4. Kirchhoff's first rule
5. Kirchhoff's second rule
6. Measurement methods

So, let's go:

1. Basic concepts

Direct electric current is a current in which the direction of particle movement is constant.
Alternating electric current is a current in which the direction of charged particles changes.
A conductor is a material, substance, or medium that conducts electric current well.
A dielectric is a material, substance, or medium that practically does not conduct electric current.
A source of electric current is a converter of any type of energy (mechanical, chemical, nuclear, etc.) into electric current.
