Role Of Resistance And Resistivity In Different Types Of Wires

Electric wires form an important part of our lives. They play an important role in supplying electricity or electrical signals from the power generating unit to our homes. Wires are made up of different types of materials. The behavior of wires changes when the electricity is supplied to a longer distance than when they are used in a circuit of a device. You must have known about the multiconductor wires, shielded and unshielded wires. But today in this blog, we will discuss the resistance and their effects in various types of wires.

All the devices either work on AC or DC power. The circuits that work on AC power, face a lot of problems such as skin effect and proximity effects like-resistivity/impedance. Let’s understand what is resistance and its effects.

Resistance reduces the movement of electric charge through the wire. Moreover, it increases when the distance is high or the length of the wire is too long. So, the resistance depends on the type of the material of the wire. For example, in the copper wire, the resistance is very less. The reason is that copper is highly conductive wire.

The resistivity of the aluminum wire is very high compared to the copper wire. This is why copper wires are used to transmit the electricity from one place to another instead of using aluminum wires. In short, it is the loss of current while transmitting or supplying the electric charge.


But resistance is good in some cases. While transmitting the electricity the heat is produced and it results in loss of energy. However, in a tungsten or tantalum wire, this heat is used to make the wire glow and produce light, which is desired in some cases. Tungsten is used to make filaments because it has a very high melting point.

The wire can get very hot and glow brightly without melting. But wires made up of Tungsten are not efficient in power transmission since most of the energy is lost in the form of heat and light.
