Electrical equivalent of heat = 1.033 J/cal Percent Difference = | 1.033 - 4.184| / (4.184) * 100% = 75% 4. DISCUSSION 2. Compare your result with the accepted value of J=4.184 joules/cal by calculating the percent difference between them. Is your result larger or smaller than the accepted value? Discuss the sources of errors. 5. CONCLUSION This experiment was completed in order for our group to have a further understanding of the electrical equivalent of heat. The lab was able to depict the relationship between power, voltage, and the J value. The equations helped clarify the units of the joule value. Common human error is prevalent in this situation due to not stopping the stopwatch at exactly two minutes each time. Also, measuring the voltage and amps could have been read inaccurately according to what was shown.
