a copper wire of resistivity 1.6x10 raise to the power -8 ohm meter has a cross sectional area of 20x10 raise to the power -4cm square . calculate the length of this wire required to make a 10 ohm coil

Open in App

Solution

R= Ï L/A
R= Resistance= 10 ohm
Ï= Resistivity = 1.6x10^-8 ohm-m
L= Length
A= Area= 20x10^-4 cm²
Substitute the values in the above formula and you can find out the length of the wire
