What is Electrical Resistance?
Electrical Resistance is the physical property of the material and it is one of the most important properties of the material as it is used to generate heat and has various applications in our daily life. Let’s define it formally as:
Electrical Resistance Definition
The property of an electrical conductor to oppose (resist) the flow of electric current is known as electrical resistance. All materials have their own electrical resistance. It is represented by R.
Electrical Resistance Unit
The SI unit of resistance is Ohm Ω (Greeks letter Omega). It was named after the German physicist, Georg Simon Ohm who gave Ohm’s law and the relation between voltage, current, and resistance. One ohm is defined as the resistance of a conductor in which a current of one ampere flows when a voltage of one volt is applied.
Electrical Resistance
Electrical resistance is the obstruction offered by the material in the flowing of the current or charge through the material. Thus, the higher the resistance the lower the amount of current passing through it. It is the property of a material that tells us about the flow of the current through the material. The substances that easily conducts the electric current are called conductors and they have very low electrical resistance, on the contrary, the substance that does not easily conducts the electric current are called insulators and they have very high resistance.
In this article, we will learn about, electrical resistance, its formula, factors affecting electrical resistance, and others in detail.
