Quantity and its units | fundamental units | SI Units of Different quantities

 In this blog, we will learn all the basic quantities used in the study of electrical engineering and also its SI units that you must know when you start your engineering course. SI units of fundamental quantity and measuring quantity both are necessary for getting an edge in the classroom guys. Let's start :




Question: What is a quantity?

Ans: A number or an amount of something (anything that can be measured is a quantity ) 

Question: What is a Unit? 

Ans:  A physical quantity, such as length, mass, energy, etc, specified multiples of which are used to express magnitudes of that physical quantity the second is a unit of time.

Quantity and Unit of terms used :  

1. Length = Metre 

2. Time = Second 

3. Mass = Kilogram

4. Area = Square Metre 

5. Volume = Cubic Metre 

6. Velocity = Metre/second

7. Acceleration = Metre/ square second

8. Density = Kilogram/ cubic metre

9. Momentum = Kilogram-metre/second

10. Work = Joule

11. Energy = Joule 

12. Force = Newton

13. Pressure = Pascal or newton/square metre

14. Frequency = Hertz

15. Power = Watt

16. Weight = Newton or kilogram

17. Impulse = Newton-second

18. Angular velocity = Radian/second

19. Viscosity = Poise 

20 . Surface tension = Newton/ metre

21. Heat = Joule

22. Temperature = Kelvin 

23. Absolute temperature = Kelvin

24. Resistance = Ohm

25. Electric current = Ampere 

26. Electromotive force = Volt

27. Electrical conductivity = Mho/metre

28. Electrical energy = Kilowatt -hour

29. Electrical power = Kilowatt or watt

30. Magnetic intensity = Oersted 

31. Charge = Coulomb

32. Magnetic induction = Gauss

33. Luminous flux= Candela 

34. Intensity of sound = Decibel

35. Power of lens = Dioptre

36. Depth of sea = Fathom 

So this is all about quantities and its SI units to remember.




( दोस्तों बहुत सरे लोगो को इनमे से ज्यादा यद् नहीं रहता आप केवल 10 याद करके देखो क्लास में आपका कमल बेमिसाल हो जायेगा )

Faraday's Law of electromagnetic induction | Lenz's law | Law of electromagnetic induction

Faradays Law of  Electromagnetic Induction : Faraday's laws state that an emf is induced in a circuit which is (i) Directly proportional to the time rate of change of flux enclosed by the circuit. (ii) Directly proportional to N the no. of turns of the circuit. Combining, the two laws, Faraday's laws of induction can be expressed mathematically as Here negative sign is due to Emil Lenz, who after Faraday's experiments suggested that the direction of the induced current is always such as to oppose the action that produced it. As we know Faraday's law as given by equation (ii.1) is one of the two basic relationships upon which the whole theory of electromagnetic and electromechanical energy conversion devices are based and today we have the generator and motor (electric) operating based on this theory. Also, Faraday was the first to identify emf of self-induction, i.e., here we have only one coil and it is connected to a de source through a switch. When current is flowin...

Emf Induced in a Rotating Coil placed in a Magnetic Field | Emf Induced | Magnetic Circuit

EMF Induced in a Rotating Coil Placed in a Magnetic Field :  👉 Consider a coil AB placed on the outer periphery of a soft iron solid cylindrical rotor. The stator poles  carry the exciting coils. When current flows through exciting coils flux is set up as shown in Fig. 1.  The rotor is rotating in the clockwise direction at a constant angular velocity of Z radians/sec. The  direction of the linear velocity (perpendicular to the plane of the coil) acting on conductor A is shown in Fig. 1 which makes an angle T with the direction of the field. The component of velocity perpendicular to  the field is v p  = v sin T .                                                                      FIG: 1 The emf induced in conductor A , e = Blv sin T Where, B = f...

Types of Network Element | Active and Passive Network | linear and Non-linear Network | Circuit elements

In this article, we will discuss what are the basic network elements and types of network elements.   Types of network elements We can classify the Network elements into various types based on some parameters. Following are the types of network elements −  Active Elements and Passive Elements    Linear Elements and Non-linear Elements   Bilateral Elements and Unilateral Elements    Lumped Elements and Distributed Elements Active Elements and Passive Elements  Active or passive based on the ability to deliver power. Active Elements deliver power to other elements, which are present in an electric circuit. Sometimes, they may absorb the power like passive elements. That means active elements have the capability of both delivering and absorbing power. Examples: Voltage sources and current sources.   Passive Elements can’t deliver power (energy) to other elements, however, they can absorb power. That means these elements eith...
