1.

If l=length, R=resistance and A=cross sectional area, then. . . .

Answer»

`RPROP(l)/(A)`
`Rprop(A)/(l)`
`Rprop(l)/(Al)`
`Rprop lA`

SOLUTION :Resistance of any equal conductor is DIRECTLY PROPORTIONAL to its length and inversely proportional to its cross-sectional area (A).
So, `Rprop(l)/(A)`.
