It is often desirable in designing an electric wiring system to be able to control a single appliance from two or more locations, for example, to control a lighting fixture from both the top and bottom of a stairwell. In home wiring systems, this type of control is implemented with three-way and four-way switches. A three-way switch is a three-terminal, two-position switch, and a four-way switch is a fourterminal,two-position switch. The switches are shown schematically in P2.40(a), which illustrates a three-way switch, and 2.40(b), which illustrates a four-way switch. If the lamp (appliance) is to be controlled from more than twolocations, four-way switches are used in conjunction with twothree-way switches. One four-way switch is required for eachlocation in excess of two. Show how one four-way switch plus twothree-way switches can be connected between a and b in P2.40(c) to control the lamp from three locations. (Hint: The fourwayswitch is placed between the three-way switches.)

What is the percentage of voltage regulation where the no load voltage is 4160 volts and its full load voltage is 4050 volts?

Without changing the configuration of the voltmeter place the positive lead into the center hole of thebarrel connector to connect to the inside contact and hold the negative lead on the outside contact of theconnector. Why is this measurement different from having the negative lead into the barrel connector and the positive lead on the outside of it?
