Answer:

we know that Resistance is given by R = ¶l/a

where ¶ is resistivity of the material

l is length of the wire .

a is area of cross section of the wire .

So R = 100×10^-6 × 1/2×10^-6

=> R = 50 ohm

Answer:

50 ohm.

Explanation:

we know that,

R=p*L/A

where p is resistivity of wire.

L is length of wire

A is area of cross section

So,R=100*10^-6*1/2*10^-6

=50ohm
