Investigation To Measure The Resistivity Of Graphite Aim The aim of the experiment is to find out the resistivity of graphite. The resistance which is measured in ohms of a resistor is applied with three basic elements. These are length (in meters) the cross sectional area which is measured in meters squared, and finally resistivity which is measured in ohms multiplied by meters. The experiment is aimed to measure resistivity of the graphite. To measure this you cannot just put a measuring device on the graphite and measure the resistivity. No resistivity is done by measuring three different readings that can be arranged in an equation. The four parts to this equation are :- A (Cross-sectional area) R (resistance) L (Length) ? (Resistivity). These put in an equation to find resistivity are:- ?= A R L So lets say if the length is doubled, then the resistance of the wire is doubled, then...
