Answer to Problem 28PQ

The estimation of the resistivity and conductivity of a roll of the pure copper pennies are 1.678×108Ωm and 5.959×107Ω1m1.

Explanation of Solution

The estimated values of pure substances are given in Table 28.2.

For the pure copper, the resistivity (ρ) and the conductivity (σ) are 1.678×108Ωm and 5.959×107Ω1m1.

Conclusion:

Therefore, the estimation of the resistivity and conductivity of a roll of the pure copper pennies are 1.678×108Ωm and 5.959×107Ω1m1.

Answer to Problem 28PQ

The estimation of the resistance of the roll of pure copper pennies is 3.7×106Ω.

Explanation of Solution

The radius and the length of a stack of 50 pennies are 10mm and 70mm.

Write the relation for the resistance of the role of pure copper pennies.

   R=ρlA                                                                                                                     (I)

Here, R is the resistance of the role of pure copper pennies, ρ is resistivity of the pure copper, l is the length of the copper role, and A is cross-section area of a copper penny.

Write the relation for the cross-sectional area of the copper penny.

   A=πr2                                                                                                                  (II)

Here, r is radius of the copper penny.

Use equation (II) in equation (I) to get R.

   R=ρlπr2                                                                                                               (III)

Conclusion:

Substitute 1.678×108Ωm for ρ, 70mm for l, and 10mm for r to find R.

   R=(1.678×108Ωm)(70mm)(103m1mm)π[(10mm)(103m1mm)]2=3.7×106Ω

Therefore, the estimation of the resistance of the roll of pure copper pennies is 3.7×106Ω.

(b)

To determine

The estimation of the resistance of the roll of pure aluminum pennies.

(b)

Answer to Problem 28PQ

The estimation of the resistance of the roll of pure aluminum pennies is 5.9×106Ω.

Explanation of Solution

Rewrite the equation (III) for the resistance of the aluminum pennies R.

   R=ρlπr2

Conclusion:

Substitute 2.655×108Ωm for ρ, 70mm for l, and 10mm for r to find R.

   R=(2.655×108Ωm)(70mm)(103m1mm)π[(10mm)(103m1mm)]2=5.9×106Ω

Therefore, the estimation of the resistance of the roll of pure aluminum pennies is 5.9×106Ω.
