  Basic Law Of Electrical Engineering  1) Ohm's Law 2) Faraday's Law 3) Lenz's Law 1) Ohm's Law        Ohm's Law state that for a   constant value of resistance the current flowing through a conductor is directly proportional to the applied voltage  That means :   R= V / I  Where  R=Tesistance of the conductor                V= Voltage across the conductor                 I= Current through the conductor   2) Faraday's Law     A)  First law :       Faraday's first Law state that whenever the magnetic lines of force linking with a coil or conductor changes an emf gats induced in the coil1 or conductor.                                  OR        First Law State that the whenever current carring conductor plac...

Basic Definition Of Electrical Engineering. Circuit or Network :      A circuit or network is an electrical configuration which electrically connects various component such as capacitors, resistors, inductors etc. Power :      Power in a dc circuit is equal to the product of voltage and current.                                               Formula :      P= V x I The unit of power is  Watt.  Power is also define as the rate of transfer of energy with respect to time. Electrical Energy :        Electrical energy is difined as the product of electric power and the time. Thé Unit of Energy is  Watt-Hour.            Formula.    E= P x I Denoted by  E= Electrical Energy                      ...

 Basic Concept Of Current, Potential Difference,Resistance and Electromotive Force (EMF) 1) Current:              The current due to flow of electrons is called as electric current. OR The movement of electrons or flow of electrons inside a conducting material. It is denoted by I and measured in Ampere.  2) Potential Difference :              Po tntial difference is the difference in the amount of energy that charge carriers have between two points in a circuit. Measured in volts. and is called as Voltage.  3) Resistance :                   Resistance is defined as the Opposition to the flow of current. Measured in Ohms.  4) Electromotive Force (EMF):            T he electrical force or pressure that causes the electrons to move in a particular direction is called as electromotive force (EMF).      ...
