`{:("Area of the"),("rod A"_T):}}=9 xx10^(-6) m^2`
`{:("Length of"),("the rod " l_T):}}=500 Omega`
`{:("Specific resistance"),("or the rod "):}}=rho_T = (R_T xxA_T)/l_t`
`rho_T = (500 xx 9 xx 10^(-6))/(95 xx10^(-2))`
`= 4500/95 xx10^(-4)`
` = 0.45/95 `
= 0.004736
`:." Resistivity of the rod between its ends "`
` rho_T = 4736 xx 10^(-6) Omega` m
