This paper will focus on single-phase ac circuits and develop the definitions for ac powers (complex power, active (real) power, and reactive power). Then, I will discuss design and development of interactive instructional virtual instrument (VI) for studying basic single phase ac circuits. These VI demonstrate how to take power measurements using a NI USB-6008 multifunction I/O device, which interfaces to the PC through a USB connector.
