What is Electricity and How it is Generated and Transmitted in Homes

There are several technology which transformed our civilization. The first advent was the wheel, the second creation was electric power, the 3rd innovation was telephone, and the 4th technology was the personal computer. Here we are going to talk about the fundamental overview of electricity. Every matter on this universe consists of an abundance of … Read more

What is Electrical Resistance

resisatnce2Btable2Bchart 1

The characteristic of a material to resist the flow of current through it, is known as resistance. When any element is subjected to an electrical potential difference or a voltage difference you will find an electric current trying to move through the element. The voltage applied over the element will be directly proportional to the … Read more

Resistivity and Laws of Resistance

Inferred2Bzero 1

Resitivity which is also known as Coefficient of Resistance is a property in a substances which causes an opposition to current flow within that substance. This can be easily calculated through formulas deduced from Laws of Resistance Laws of Resistance The amount of resistance in any material will depend on the following aspects:   1) … Read more

Temperature Coefficient of Resistance

From our earlier discussions we have understood that electrical resistance of all elements changes in response to the variations in its temperature. Temperature coefficient of resistance is defined as the magnitude by which the electrical resistance of a material changes in response to each degree change of temperature. If we consider  a conductor with a  resistance … Read more

Resistances in Series and Resistances in Parallel

parallel 1 1

Several electrical resistances could be hooked up both in series or in parallel, likewise, in excess of 2 resistances may also be joined in groups of series and parallel each. In this article we are going to primarily talk about series and parallel resistance combination. Resistances in Series Assume there are, 3 resistors, R1, R2 … Read more
