Question

A copper wire of cross
sectional area 0.01 mm2 is
used to prepare a
resistance of 1K22. The
resistivity of copper is
1.7x10m Calculate the
length of the wire​

Answer 1

Answer:

i will study and tell u..........

Answer 2

Answer:

No Resistivity does not depends upon thickness as well as length of the conductor. But it depends on material and temperature of that conductor.

RESISTANCE = ROW•LENGTH/AREA OF CROSS SECTION . ROW(resistivity) = Resistance × Area of cross section/Length..

Ans:Row=r×a/x

Answer is 588.23 m
