Nichrome has higher resistivity and is not oxidizable at higher temperatures.
The equation related to the resistivity of the material is given as:, where is the resistivity, is the resistance, is the length, area of cross section.
Nichrome is used as an alloy consisting of nickel and aluminum used in the resistor wire.
High resistivity represents the that the substance has higher resistance can can resist the flow of current.
Resistance is a property that opposes the flow of current.
If the substance has low resistivity then the resistance of the substance is low, thereby allows the flow of current
Substance whose resistance is low is said to be a good conductor. Hence, Nichrome has higher resistivity.
