In order to study the working of an electrolytic cell and the phenomena of electrolysis it is important to know the working of a galvanic or a voltaic cell that generates electrical energy from its chemical reaction. In a simple voltaic cell a zinc plate and a copper p..

. Under ordinary conditions the free electrons in a conductor move randomly in such a way that the net flow of charge across any section of the conductor is zero. No current exists in a conductor, unless a potential difference is applied between the ends of the conductor. Conventionally, the e..

. No current exists in a conductor, unless a potential difference is applied between the ends of the conductor. Conventionally, the electric current is said to flow from a higher potential to a lower potential while the electrons flow from a lower potential to a higher potential i.e., the..

Electric Charge - It is very difficult to define, what an electric charge is? The word 'electric' is derived from the Greek word 'elektron' meaning amber. The existence of charges were known when charged particles were produced by rubbing (due to friction) of suitable ..

Electric Charge - The word 'electric' is derived from the Greek word 'elektron' meaning amber. The existence of charges were known when charged particles were produced by rubbing (due to friction) of suitable materials. These facts are demonstrated by simple experiment..

Conclusion - Principle of electrostatics and electromagnetism play a very vital role in all modern scientific developments. Coulomb's law may be regarded as merely a special case of Gauss' law or we can say Gauss's law is generated form of Coulomb's law. Gauss' law makes it possible to calculate in..

Thermoelectricity refers to the phenomena that occur at the junctions of dissimilar conductors when a temperature difference exists between the junctions. The same phenomenon occurs within a single conductor too, with the two ends are maintained at different temperatures. In this section,..
