Difference between resistor and resistance

Resistor and resistance are two of the most fundamental concept in electronics. These two ideas play a vital role in almost every electronic device we use today. We all know that a resistor is an ability to resist the flow of electric current through it,  while resistance is the property by virtue of which a material opposes the flow of current through it is called as the resistance. Let us have a deep insight into the comparison between a resistor and a resistance. 

Definition of Resistor:

A resistor is an electric and electronics component with a predetermined electrical resistance i.e, 1 ohm, 10 ohms, 100 ohms, 10000 ohms, etc.

Definition of Resistance:

Resistance is the property of a conductor, which can determine the quantity of current that passes through it when a potential difference is applied across it. 

The main key difference between resistor and resistance are listed below:

  • A resistor, any material which has some resistance is called a resistor, While the resistance is the property by virtue of which a material opposes the flow of current through it is called resistance. 
  • The resistor is a component with a mainly resistive behaviour when used in an electrical circuit when capacitance and inductance can be considered negligible, Resistance is a measure of the quantity of this resistive behaviour.
  • The resistor is the equipment/component used to add resistance in the given circuit, While the resistance is the property of the conductor which opposed the flow of current flowing through it at a given voltage. R = VI
  • The resistor is an electric company with a predetermined electrical resistance like 1 ohm, 10 ohms, 100 ohms, 10000 ohms, etc.  Resistance is the property of a conductor, which can determine the quantity of current that passes through it when a potential difference is applied across it.
