What is Resistance : Definition, Formula and Laws

The flow of electrons in a material produces electricity. These electrons do not travel in a straight path but have to undergo collisions. Based on the amount of electricity the material allows to pass, all materials are categorized as...

What is Electrical Resistance – An Overview

The materials are categorized into two different types namely conductors and insulators. A conductor allows the flow of current whereas an insulator doesn’t. So the conductor materials should require the resistor components in their structure....

Difference between Resistance and Resistivity

The resistance and resistivity concept is one of the most fundamental as well as an essential part of the concept of current & electricity. The major difference between resistance and resistivity of the material is that the resistance...

Temperature Coefficient of Resistance

In electrical or electronic engineering, when the flow of current supplies through a wire then it gets heat because of the wire’s resistance. In perfect condition, resistance must be ‘0’ however that doesn’t take place. When the...

What is Resistivity : Definition and Its Formula

When a potential difference is applied across a material, the electrons in the material start moving from the negative electrode to positive electrodes, which produces current in the material. But during this movement of electrons, they...
