© S. J. Bitar – Educational Services - 2004 - - 2 ECE 2011 - Project #1 Resistor Power Limit / KVL Verification Acoustic Rangefinder Abstract This project investigates the power limitation of a resistor, the verification of Kirchhoff’s Voltage Law (KVL), and the operation of a simple acoustic rangefinder. Initially, a standard 0.25W resistor is subjected to a destructive test whereby the “magic smoke” is allowed to escape thus yielding the resistor useless at the end of the experiment (although a valuable lesson is learned). Kirchoff’s Voltage Law (KVL) is then subjected to the most excruciating scrutiny and yet manages to prevail despite all attempts to disprove it. And finally, a deceptively simple microphone and speaker are converted into a most amazing acoustic rangefinder whereby the speed of sound, in the halls of Atwater Kent, is found to travel faster than professors leaving WPI on a Friday afternoon.
