Many housemasters silently smile when they think back on some of the student exploits they've witnessed during their time in the dorm. "There are things I know a lot about that I wish I didn't," Randolph admits, "but I wouldn't trade the relationships we've made with students for any other experience."
In the summer, most housemasters get a break and some time to themselves. This year Stewart and his son, Cameron, were on a mission to visit every Major League baseball park in North America; Smith and Mellquist head to Maine each year to exchange the sounds of construction and loud music for birdsong and the lull of the Atlantic. They all come back in the fall, refreshed and ready for the energy of the students. "It's always good to get away," says Larry Anderson. "And it's always good to get back." 
Voltage is the difference of electrical potential between two points of an electrical or electronic circuit, expressed in volts. It measures the potential energy of an electric field to cause an electric current in an electrical conductor.
Most measurement devices can measure voltage. Two common voltage measurements are direct current (DC) and alternating current (AC).
Learn the fundamentals of creating an AC or DC voltage measurement system. See how to properly connect the signals to your data acquisition system for accurate acquisition.
