What Are the Correct Units for p in the Equation R=pl/A?

[phyuk2]

Homework Statement

rearrange to make p the subject then work out the units for p

R - resistance or wire
A - area in m²
l - length

Homework Equations

R=pl/A

The Attempt at a Solution

p = AR/l

(m² x m²kgS^-3A^-2)/m

Resistance is ohms which is m²kgS^-3A^-2 I think.

p=m³kgS^-3A^-2

Yes, your working is right. The units for resistivity is the ohm.metre or m³kgs^-3A^-2
