The concept of electrical resistance can be explained by comparing it with the hydraulic system. When the current flows through a wire, it is like fluid flow through pipe and the voltage loss that happens across the wire corresponds to pressure drop which gives a force for water through a pipe. So, in this analysis resistance is termed as what amount of pressure is necessary to accomplish specified flow. To be clear, let us look into the below concepts … [Read more...]
Difference between Resistance and Resistivity
In the electrical and electronics industries, the concepts of resistance and resistivity are the most important ones. One has to be clear regarding why these topics hold prominence and what are differences and comparison? The foremost difference is that resistance opposes the electron flow, while resistivity defines the material’s resistance having the corresponding dimension. So, here is a detailed view of all these topics. This article discusses an … [Read more...]
What is Specific Resistance : Formula and Its Affecting Factors
Specific resistance is the measure of the conductivity of a particular element and it is also known as electrical resistivity. Based on the value, the conductivity, and hence the electrical characteristics of the element are evaluated. This parameter is often used to analyze the electrical conductivity of a particular element, and hence have prime importance while selecting the elements. Some applications need elements that have superior electrical … [Read more...]
