Question

Which formula of resistivity is correct?

Answer 1

Hi there,,

The formula for resistivity is
Rho=Rl/A
Here rho=resistivity
R=Resistance
L=length
A=area

Thanks

Answer 2

Here is the answer of your question :-

# The correct Formula of restivity is :-

p (rho) = R A ÷ I

Restivity is denoted by p (rho).

Here R is restivity
A is area of cross section and
I is lenght.

# S.I unit :-

Ohm meter.

Hope it helps you.
