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.
When planning your kitchen redo, the first step is setting a budget. Every remodeling project is unique, and costs vary depending on the homeowner's budget, tastes, and priorities (a minor redo can be $5,000, while an upscale overhaul can easily top $75,000). In general, however, materials account for 80 percent of the budget, while labor costs represent 20 percent.
