Answer:
the resistivity of the wire is approximately 0.0002 ohm * m.
Step-by-step explanation:
To calculate the resistivity of a wire, you can use the following formula:
resistivity = resistance * length / (area of cross section)
Plugging in the values given, we get:
resistivity = 10 ohm * 4 m / (0.1964 x 10^-6 m^2)
This simplifies to:
resistivity = 2.0256 x 10^-4 ohm * m
So the resistivity of the wire is approximately 0.0002 ohm * m.
