Distinguish between resistance and resistivity |
|
Answer» resistevity is not having 2terminals but resistance have terminals Resistance - which oppose the flow of current is known as resistance.Resistivity- the resistivity of a substance is numerically equal to the rod which is 1m in length and 1square metre area in cross section. Resistivity - resistivity is the measure of resistance of a material and in other words up to what extent will the material resist currents flow Resistance - unit R ,it is proportionally constant for the given metal at given temperature and is called resistance the graph between v and I is always a straight line with slope equal to R |
