Ohms law and kirchoff's law are the basic principles to analysing simple circuits. Basically as an electrical engineer, every principle is very important.
ohms law
kirchoffs current and voltage laws
superposition theorem
milmanns theorem
maximum power transfer theorem
if you are asking for an explanation the current flowing through a conductor is directly proportional to the voltage across it provided the temperature is constant
Kirchhoff's Law's.
If you are a student, this is not what is expected. Be wise to use the net or refer to books to ascertain that for which you are looking for an answer.
Can someone gives me two important laws of principles of electrical engineering.
