Answer:
b.
Explanation:
The voltage drop can be calculated using the formula: [ V_{\text{drop}} = 2 \times I \times R \times L ]
Where:
( I ) is the current (26.5A)
( R ) is the resistance per 1000 feet for No. 8 stranded conductors (approximately 0.64 ohms per 1000 feet)
( L ) is the one-way length of the wire (145 feet)
First, we calculate the resistance for the given length: [ R = 0.64 , \Omega/kft \times \frac{145}{1000} = 0.0928 , \Omega ]
Then, we calculate the voltage drop: [ V_{\text{drop}} = 2 \times 26.5 , A \times 0.0928 , \Omega \times 145 , ft ] [ V_{\text{drop}} = 5.98 , V ]
This calculation assumes a single-phase circuit and uses the approximate resistance for No. 8 stranded conductors. The actual resistance can vary based on the specific conductor material and manufacturer specifications
