Answer:
The conductivity of the material from which the conductor is made is 2.95 x10⁶ [S. m⁻¹] .
Explanation:
L= 1.1m
S= 0.91 mm²= 9.1 x10⁻⁷ m²
I= 4.4 A
V= 1.8V
[tex]\frac{V}{I} =R\\\\\frac{1.8V}{4.4A} =R= 9/22 ohms[/tex]
R=9/22Ω
[tex]R=\frac{L}{σ . S} \\\\Conductivity=sigma=\frac{L}{R.S} \\\\Conductivity= \frac{1.1m}{9/22 ohms . 9.1 E10 (-7) square meters}[/tex]
Conductivity=2.95 x10⁶ [S. m⁻¹]
