Question

The resistance of a conductor of length l is p. if its area of cross section is q.

What is its resistivity? What is its unit?
​

Answer 1

Answer:

R = ρl/a  

l = p  

a= q

ρ = Ra/l

Explanation:

easy bro, just simple maths

Answer 2

Answer:

Resistivity, electrical resistance of a conductor of unit cross-sectional area and unit length.

Resistance = resistivity × length / area

p = resistivity × l / q

Resistivity = p×q/l
