What is resistivity and resistor?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Resistivity is a material property that uantifies how much a material opposes current flow, measured in Ω·m.
Resistor is an electrical component designed to provide a specific amount of resistance in a circuit, measured in ohms (Ω).
Think of it this way: resistivity describes the material (like copper or carbon), while a resistor is a manufactured device made from resistive materials to control current in electronic circuits. Resistors are labeled with color codes or numbers indicating their resistance value.
