Question

A copper wire of radius a = 0.300 mm has an aluminum jacket of outer radius b = 0.385 mm. There is a current i = 2.34 A in the composite wire. Take the resistivity for copper and aluminum to be $1.69 \times 10^{-8} \Omega \cdot m$ and $2.75 \times 10^{-8} \Omega \cdot m$. Calculate the current in (a) the copper and (b) the aluminum. (c) If a potential difference V = 16.2 V between the ends maintains the current, what is the length in meters of the composite wire?

Name: A copper wire of radius a = 0.300 mm has an aluminum jacket of outer radius b = 0.385 mm. There is a current i = 2.34 A in the composite wire. Take the resistivity for copper and aluminum to be 1.69 × 10^-8Ω· m and 2.75 × 10^-8Ω· m. Calculate the current in (a) the copper and (b) the aluminum. (c) If a potential difference V = 16.2 V between the ends maintains the current, what is the length in meters of the composite wire?
