Question

the resistance of conductor is 100ohm the resistivity of conductor is 10 ohm meter if the cross sectional area given wire is 10cm square what is the length of thhe conductor​

Answer 1

Answer:

Length = 0.01m = 1cm

Explanation:

Conductivity (¶) = 10 ohm-m

Resistance (R) = 100 ohm

Area (A) = 10 sq. cm = 10^-3 sq. m

Length (L) = ?

$R= \rho \frac{l}{A} \\ 100 = 10 \times \frac{l}{ {10}^{ - 3} } \\ l = 10 \times {10}^{ - 3} = {10}^{ - 2} = 0.01m$

Thus, length = 0.01m
