what is Ohm’s Law

Ohm’s Law stated that The current flowing through the conductor is proportional to the applied voltage and its remain constant if the temperature and other condition remain constant .Thus           Current =Voltage applied /Resistance of circuit         Resistance =Voltage applied /Current in the circuit ...Read More

Fleming’s Left hand rule

what is Fleming’s left hand rule?According to Fleming’s left hand rule When a current carrying conductor is placed inside a magnetic field ,a force act on the conductor ,in a direction perpendicular to both the direction of current and magnetic field To determine the ...Read More

Conductance ( G )

Conductance is the reciprocal of resistance ( R ) .Thus                G  =  1/R  The Unit of Conductance is mho                                    ...Read More

What is Resistance

Resistance is the property of a substance due  to which its oppose the flow of electron i.e electric current through it .The unit of R is Ohm (Ω ) Metal ,Acid and salt solution are good conductors of electricity . Silver ,copper ,Aluminum offer ...Read More

Electromotive Force

Electromotive force or potential of a body is the work done in joules to bring a unit electric charge from infinity to the body .It is expressed in term of Volts. ( V )             The potential difference is defined as which caused ...Read More

What is Electric Current?

Flow of charge is called electric current .It is said to be exist when there is net flow of electric charges through a region Unit is coulomb per second                   I (Ampere) =Coulomb/Second                        I = Q / t One the basis of flow ...Read More
