What are the basic things that all electrical engineers should know?

All electrical engineers must know following things:

I would like to start with generation then transmission, distribution & at last utilization of electricity.

Basics of electricity generation technologies including conventional & non-conventional ways of electricity generation. Knowledge of different factors e.g. load factor, demand factor, etc.

Transmission & distribution voltage levels & their classification. Models of transmission lines (pi, T,etc.) their analysis. One should also know about basics of HVDC transmission. FACTS(Flexible AC Transmission System)

Laws, theorems & basic rules: Circuit analysis: Ohm’s law, Kirchoff’s Current & Voltage law, Maximum Power Transfer Theorem. Electro-magnetism & electromagnetic induction: Dot & cross convention, right hand thumb rule, Fleming’s left & right hand rules, types of emf induction.

Concept of impedance & admittance. Different types of loads (R, RL, RC, RLC); their series & parallel connections along with phasor diagrams.

Types of powers i.e. Active, Reactive, Apparent & complex power.
Concept of power factor; effects of different types of loads on power factor.

Types of supply & load connections: Basics of single phase & three phase connections such as star & delta connections, voltage & current relations in balanced star & delta connected loads.

Working principles of DC motors (shunt, series, compound) & knowledge of their characteristics to understand their applications.
Working principles of single phase & three phase AC motors (induction, synchronuos, etc.) & knowledge of their characteristics to understand their applications.

Working principles of transformers, types of connections & respective applications.

Knowledge of energy conservation & simple techniques to achieve it.

Basic operation principles of all household electrical appliances.
Basic knowledge of Power Quality & effects of different types of loads on power quality.

Basic knowledge of Solar PV & Wind energy generation systems.
And last but not the least, CONCEPT OF EARTHING/GROUNDING !

Hope this helps!

Thanks a lot!
