Learn about the physics of resistance in a wire. Change its resistivity, length, and area to see how they affect the wire's resistance. Predict how changing each variable will affect the resistance.
I just purchased crackle subway tile (3x6) for our backsplash. As I was shopping around it seemed that $12-15 per square foot was the average price. You can get cheaper but they were VERY basic. I ended up with a Sonoma tile which was hand molded and cost $20 square foot.
1 On average, installing a backsplash can range in price from $13 to as much as $24 per square foot. 2  This will not include the tile and supplies, but is for installation only. 3  For example, a 25 square foot space could cost anywhere from $325 to as much as $600.
