Alternating current (AC) :-

                                                                       Alternating Current is the flow of charge that revers its direction periodically is known as Alternating current.AC current is operating on 50 to 60 hz frequency depending on Country.

According to Wikipedia:- Alternating current (AC), the flow of electric charge periodically reverses direction.

For Example : Wapda Supply 

Character wave Form Of AC :-

Ac has Four Wave Form

1. Sinusoidal wave 

    

       2.  Square Wave

                                    

     3.  Triangle wave

    4.  Complex wave

==>>>>>>>>Note  Ac will always have complex shape

                                            

Direct Current (DC) :-

                                                        Direct Current is the flow of charge that does not chant its Direction (unidirectional) is know as Direct Current.

According to Wikipedia :- Direct current (DC) is the unidirectional flow of Electric Charge.

Dc has not frequency

Engineering Drawing 

                                                          An engineering drawing, a type of technical drawing, is used to fully and clearly define requirements for engineered items. Engineering drawing (the activity) produces engineering drawings (the documents)

Simply

            "To Enable Students To Learn And Develop Engineering Drawing Skills "

1. Electrical Drawing
2. Civil Drawing
3. Mechanical Drawing

Electrical Drawing 

                                Electric substations ,Equipment's Layout , Schematic Diagrams of substations, Lighting and Power Distribution Boards, Electrical Symbols and One line diagrams of typical Power System

Civil Drawing

                          Plane, Elevation ( Front,Right and Left ) And Details of buildings

Mechanical Drawing    

                                   Use Of Drafting Instruments, Basics drafting and Technics and the Drawing and lettering, dimension, Projection and Section of Slides,Orthography Projections, Isometric Views with Particle to Piping and Ducting  And Partic Assembling Drawing

What is Physics ?

"Physics Is the branch of science that deals with the study of matter and energy and there mutual relationship is known as Physics"

For example:-
1:-  Atomic Bomb Is the invention of Physics
2:-  Tv and other electronic devices are working on the principal of Physics
3:-  Capacitor,Inducter and Resistor plays important role in the field of Physics
4:-  Airplane, Railways Business and the other transport are working on the principal of Physics
5:-  Computers, laptops and the other devices are working on the principal of Physics
6:-  Rockets and Satellite also working on the principal of Physics
7:- In our daily life wheels, pulies also working on the principal of Physics

Branches Of Physics :-

1   Mechanics Physics :-

                                             Mechanics Physics is the branch of physics which deals with the Motion of  Materials  object under the action of forces is known as Mechanics Physics.

2   Optics Physics :-

                                      Optics physics is the branch of physics which deals with the nature of light properties is known as Optics Physics.

3  Thermodynamics Physics :-

                                                           Thermodynamics Physics is the branch of Physics which deals with the transformation of heat energy into other forms of energy is known as Thermodynamics Physics.

4   Atomic Physics :-

                                        Atomic Physics  is the branch of physics which deals with the study of structure and properties of in individual of Atom is known as Atomic Physics.

5   NuclearPhysics :-

                                           Nuclear Physics is the branch of physics which deals with the Structure and the study of Nuclear is known as Nuclear Physics.

6  Bio Physics :-

                                The Study of Biology is Based on the principal of Physics is Known as Bio Physics.

7  Astro Physics:-

                                  Astro Physics is the branch of physics which deals the study of heavenly bodies is known as Astro Physics.

Ohm's Law :-

      "Stats That Voltage is Directly related to current and Resistance"

Mathematically :-

           V = IR

           I  = V/R     

           R = V/I

Graphically  :-
