Brad again. believe it or not, this subject was next on the list for discussion about another series of tests concerning the verification of a differernce in total power output of 2 test circuits. (again to verify the results of a
Simply, the caloriemeter we created for our test was made from a film canister, styrofoam beads and the probe from the outdoor part of an indoor/outdoor thermometer. The probe was connected in direct contact with a small array of lights(varible resistor/load and heat source), Next, place load into the canister and pack with the beads. And most important, all the tests were performed in a room that maintained a stable and constant temperture.
Since the point of the test was to convert electrical energy into heat and to record the temperture over time. We next created a "power under the curve" on graph paper and started counting the squares!!!
We performed a total of 3 test which included a calibration test by heating the probe to a certain temp and chart the amount of time it takes to reach room temp. This way we could confirm that the next 2 tests maintain the same rate of "heat decay".
The therory is: the circuit that produced the most squares on the graph paper. sent the most total power to the load..
My question is does this appear to be a good way to perform this type of test? Any other thoughts you can give are appreciated.
Many Thanks Brad
