Derive roh formulaRA/L

1.	Derive roh formulaRA/L
Answer» tion:Resistivity is the resistance per unit LENGTH and cross-sectional AREA. .We know that R = ρ L / A. Thus we can DERIVE the expression for resistivity from this formula. ρ = R A / L, where R is the resistance in ohms, A is the area of cross-section in SQUARE meters and L is the length in meters.Plz mark me BRAINLIEST.
