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.
In addition to the cost of the subway tiles used to build the backsplash, homeowners undertaking this type of a home remodeling project will need to plan for some additional expenses. The costs of supplies such as grout and sealant add an average of $1.51 per finished square foot of backsplash. The average hourly rate of labor for an experienced tile setter to create the backsplash is $61. This installation cost is based upon a basic backsplash consisting of a rectangular shape and one level. Homeowners desiring a more complex backsplash configuration or multiple levels will find that labor costs are higher.
