Ohm’s Law

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        Potential across resistance ...Read More

Law of resistance Resistance

Resistance of conductor depend upon Length of conductor —-its varies directly with the length; Cross-sectional area of conductor —its varies inversely with the cross-sectional area of conductor Its resistivity i-e the nature of composition etc of the material of which conductor is made up ...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

What is 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 .Electromotive force is measured in Volts. ( V ) The potential difference is defined as which caused current to flow ...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
