1. Set your digital multimeter to the resistance range. (If
you do not have an auto-ranging digital multimeter, you will need to find the
range that will yield the best readings.)
2. Insert the black test lead into the common jack on the
digital multimeter.

Figure 6-3 shows a floor plan for a detached garage. What is
the width of wall space A at the front of the garage?

Electric shock is a result of an electric current flowing
through the body. The amount of current that flows through the body is
determined by the makeup of the body (lean body tissue or fat), the entry and
exit points on the body, the degree of moisture present on the skin, and the
amount of voltage applied to the body. Using the ohmmeter function of a digital
multimeter, you will measure your body resistance between several points. Then
you will perform some simple calculations to determine the amount of voltage
required to cause a fatal current to flow through your body

1. If you cut a piece 106 inches long from a 120-inch board, how many inches are left?
2. From a supply of 2,643 feet of tubing, you use 114 feet. How much tubing is left in the supply?
3. If 145 cubic yards of earth need to be excavated for a house foundation and 70 cubic yards can be used as fill on the site, how much must be disposed of elsewhere?

1. List seven safety rules for electricity given in this
chapter. You may refer to the chapter as you list these rules, but do not copy
word for word from the chapter. Use your own words.
2. What will happen if a multimeter set in the amp position
is applied to the hot and neutral conductors of a live circuit?

The branch circuits for a house are listed in Figure 6-2.
What is the total current load for the house?

1. A house requires ductwork in the following lengths: 26
feet, 18 feet, 9 feet, 8 feet, 8 feet, 5 feet, and 3 feet. How many total feet
of ductwork are needed?
2. A house requires 12 cubic yards of concrete for the main
slab, 6 cubic yards for the footings, and 7 cubic yards for the garage. How
many total cubic yards are required for the house?

What is the total length of the house shown in the partial
floor plan in Figure 6-1?
