Understanding the Concept of Voltage Drop
A whiteboard displays handwritten electrical engineering calculations comparing aluminum and copper wire costs for a 350-foot run, showing aluminum costs $2059.88 while copper costs $5207.14, with the word 'ALUMINUM' circled in orange. The calculations are based on a 3% voltage drop formula for 240V systems, with the final wire sizes and prices clearly written in red and orange markers. Several Expo dry-erase markers are visible at the bottom.
