Calculate the resistance of a 50 m length of wire with a cross-sectional area of 0.01 square mm and a resistivity of [tex]5 \times 10^{-8}[/tex].

Asked by PrincessManshi

Answer (2)

[Resistance R = resistivity * length / area
R = 5 10^{-8} * 50 m / 0.01 * 10^{-3} * 10^{-3}
R = 250 Ohms ]

The resistance of the 50 m length of wire with a given resistivity is calculated using the formula R = ρ A L ​ . After converting the cross-sectional area to square meters and substituting the values into the formula, the resistance is determined to be 250 ohms (Ω).
