Question

3. A 250-foot length of solid copper bus bar, shown in Figure 3-34, is used to connect a voltage source to a distribution panel. If the bar is to have a resistance of 0.02 $Omega$ at 20° C, calculate the required height of the bus bar (in inches).

Step 1

- Length of the bus bar, $ l = 250 $ feet - Resistance, $ R = 0.02 $ ohms - Temperature, $ T = 20^\circ \text{C} $ - Width of the bus bar, $ w = \frac{1}{4} $ inch - Resistivity of copper at $ 20^\circ \text{C} $, $ \rho = 1.68 \times 10^{-8} $ Show more…
