Question

Complete the figure given below so that its area is 12 sq. cm. Lets do it .​

Answer 1

Answer:

Answer:

Given:

⠀⠀⠀⠀⠀Resistance = 10 ohm

⠀⠀Radius of wire = 0.01 cm

⠀⠀⠀⠀⠀⠀⠀⠀= 0.01x10^-2

⠀⠀⠀⠀Resistivity = 50x10^-8 ohm metre.

⠀Formula:

⠀⠀⠀⠀Length = Resistance$\times$ area/Resistivity

⠀⠀⠀⠀⠀Area = 3.14x10^-8 sq.m

So length = 10*3.14x10^-8/50x10^-8

⠀⠀⠀⠀⠀⠀= 31.4/50

⠀⠀⠀⠀⠀= 0.628 m
