I used the W = I2Rt to calculate the work done and Q = (mwcw+mccc+mhch)(Tf-Ti) to calculate the heat produce. In my understanding the 2nd run with higher current should produce more heat than the first correct? However my result is showing lower heat produced than it should for the amount of...
I recently finished a lab experiment on heating effect of an electric current(heating water by running current through a resistor). I did two runs of the test first at 2 amp and second at 3 amp. The first run shows a small % error however the second run gave me 26% error. What would explain the...
