Historia de la Química (Física Química). Classic Chemistry

La sección Classic papers de la web Classic Chemistry , del profesor estadounidense de Física Química Carmen Giunta, nos ofece un magnífico recopilatorio de artículos que describen hallazgos importan ...

Insulators

"Insulators, also called dielectrics, don't conduct charge. In insulators, there is no conduction band so charge does not move to any appreciable extent. Dialectric strength, also called breakdown v ...

Electrons - Quantization of Electric Charge

"Electric charge is the transfer of electrons from one material to another. So negative charge means that there is an excess of electrons while positive charge is a deficiency of electrons. Quantiza ...

Electric Potential

"Electric potential is the ratio of electric potential energy and test charge. The concept of test charge is explained in electric fields. Positive charges prefer high electric potential while negat ...

Electric Force

Hipervinculo Física

Electric Force

"Opposite electric charges attract each other while like electric charges repel each other. This force of attraction and repulsion is called electric forces. Coulombs law states that force of attracti ...

Electric Field

Hipervinculo Física

Electric Field

"An electric field is the ratio between the force felt by a small charge and that small charge. The small charge is called the test charge. This force can be found using Coulomb's law. Electric field ...

Electric Current

"Electric current is the rate of charge flow as charge moves through a conductor. Current is conventionally taken to be in the direction of positive charge flow. Current is caused by differences in ...

Electric Circuits

"Electric circuits are one or more loops of wire which allow current to flow all the way around, usually driven by a battery which maintains a potential difference to keep current flowing. Light bulbs ...

Resistors in Series

"Resistors in series are successive resistors in which the same current cannot simply go through one resistor. We can add resistors, but it increases the resistance of the whole network. If one resis ...

Resistors in Parallel

"Resistors in parallel consist of two separate independent circuits so that when the current reaches a resistor, the current can choose which to go through. Most homes are wired in parallel so that u ...
