In this post, I am sharing a list of basic electrical laws and theorems. Listing out these laws and theorems will be helpful for electrical students.

All these different laws and theorems belong to electrical and electronic studies.

Before this article, I have explained the concept of an electrical circuit. They are used to solve the electrical network.

To solve these electrical circuits, you also need to apply multiple Electrical Laws and Theorems so that you can calculate the required values for various parameters.

Some laws apply to the AC and DC systems.

Let’s see the most important electrical Laws, theorems, and rules, one by one.

What are the basic Laws of Electrical Engineering?

Here are listing of the most important top 13 electrical and electronics laws.

1. Ohm’s Law

Learn here detail, electric ohm’s law

Here is a simple calculator to calculate Current from Resistance and Voltage using Ohm’s law.

2.Electric and Magnetic Circuits Kirchhoff Law

There are two types of Kirchhoff’s Law.

  • Kirchhoff Current Law
  • Kirchhoff Voltage Law

Learn more detail about Kirchhoff’s law. I have explained the applications.

3. Joule’s Law of Electrical Heating Effect

  • First Law of Joule
  • Second Law of Joule

4. Newton Law of Motions (Physics laws)

  • First Law of Newton
  • Second Law of Newton
  • Third Law of Newton

Note: These are Physics laws and also useful in Electrical.

5. Electrostatic (Coloumb) Law

  • First Law of Electrostatic
  • Second Law or Coloumb Law of Electrostatic

6. Faraday’s Law Of Electromagnetic Induction

  • First Law of Faraday
  • Second Law Faraday
  • Third Law or Lenz’s Law of Faraday

7. Biot Savart Law for Electric and Magnetic field

8. Ampere’s Circuital Law

9. Gauss’s Law

10. Lenz’s Law

11. Curie’s Law

12. Hopkinson’s Law

13. Wiedemann–Franz law

These list of electrical laws are applicable to both electrical and magnetic circuit.

Electrical and Electronic Network Theorems

In the electrical and electronic circuit, theorems help to simplify and to analyze the network.

Mostly these theorems are useful for the DC sources.

Here is the list of 9 theorems.

  1. Superposition Theorem
  2. Thevenin Theorem
  3. Norton Theorem
  4. Millman’s Theorem
  5. Reciprocity Theorem
  6. Compensation Theorem
  7. Maximum power transfer Theorem
  8. Star-Delta transformation Theorem
  9. Delta-Star transformation Theorem

Electrical Machines Rule

The most important rule in electrical machines study is Fleming’s rule. Mainly, this rule is used for motors and generators.

Following are two Fleming’s rules for Machines:

  • Fleming’s Right-Hand Rule
  • Fleming’s Left-Hand Rule

The first right-hand rule is applicable to the generators. And the second left-hand rule is applicable to the motors.

This article is all about listing different basic electrical laws and theorems. I will explain each law and theorem in my upcoming articles.

Thanks for reading!
