Question

derive the equation for rho? class 10 science??#cbse​

Answer 1

Answer:

hey friend look

rho is constant of proportionality and called electrical resistivity it comes as follows

R is directly proportional to length of conductor

R is directly proportional to 1/area of cross section so R is directly proportional to L/A

to remove that sign p(rho) is used

R=p(L/A)
