# General Basics of Electricity

in this Topic, I will review with you all the electrical basics, Although most of us may know it or know most of it, but trust me, if anyone need to be expert in a field , he must be involved in all the basics of this field.

I will not explain in detail this basics , but I will put here summary files which be short but be enough to refresh your electrical basics totally.

if anyone need to be expert in a field , he must be involved in all the basics of this field"

1- Electrical circuits basics:

Electrical circuit definition - Electrical charge - Conventional electric current - Electric current – Voltage - Conductors and insulators - DC circuits - AC circuits.

2- Electrical circuit’s configuration

Electrical circuit elements - Resistance, Resistivity and Conductivity – Capacitor – Inductor - Resistor combinations - Capacitor combinations – Impedance - Impedance combinations – Admittance - Resonance circuits.

3- Batteries

Carbon Zinc batteries - Lead-acid batteries – Alkaline batteries.

4- Electrical Measurements

Moving coil meters – Voltmeter – Ammeter – Ohmmeter - Galvanometer.

5- Electricity and Magnetism Laws

Coulomb’s Law - Gauss’s Law - Electric field - Ampere’s Law – Biot - Savart’s Law - Faraday’s Law - Lorentz Force ‘s Law - Left and Right hand rules - Maxwell’s equations.

6- Electrical circuits Law and Theorems

Kirchhoff’s Law - Ohm’s Law - Resistivity calculations - DC electrical power - Resistor losses - RMS and effective values - AC power - Superposition theorem - Thevenin’s theorem - Norton’s theorem - Delta /Star Transformation.

in the next Topic, I will talk about the Electrical Systems Configurations.
