ENGINEERING
The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes
Which combines the fields of science and mathematics and applies it to solve real problems to improve the world around us
Ability to create innovatively new concepts bond by certain laws or rules and regulation.
ELECTRICAL ENGINEERING
It is a field of engineering that generally deals with the study of electrical machineries and electrical devices which is working under the principle of electromagnetism or electro magnetic induction and its applications
A common theme is the use of electricity and electromagnetism for the generation, transmission, distribution, storage, control and conversion of Electrical energy
It now covers a range of subtopics including power, electronics, control systems, signal processing and telecommunications
The Right Hand Rule
The direction of the magnetic field surrounding the conductor can be found using your right hand
Position the thumb of your right hand pointing in the direction of conventional current (Positive to Negative) and your fingers will wrap around the conductor in the direction of the induced magnetic field.
FLEMINGS RIGHT HAND RULE
Stretch the fore finger, middle finger thumb of your right hand so that they are mutually perpendicular to each other. Then the fore finger will indicate the direction of magnetic field, the thumb will indicate the direction of motion of the conductor then the middle finger will indicates the direction of induced current.
FLEMINGS LEFT HAND RULE
Stretch the fore finger, middle finger thumb of your left hand so that they are mutually perpendicular to each other. Then the fore finger will indicate the direction of magnetic field, the middle finger will indicate the direction of current flow in the conductor then the thumb will indicates the direction force.
