Unformatted text preview: The total resistance was measured and the known resistance was subtracted from this value to determine the resistance of the unknown resistor. The same was done for resistors in parallel but a different formula was used to solve for the unknown resistor. Resistance for resistors in parallel is (1/r1+1/r2)^1=resistance and this formula was used to solve for the unknown resistor. The dependence of resistance on temperature was observed when we heated a copper wire and plotted resistance versus temperature over 25 minutes. The trend we observed was that as temperature increases resistance of a material increases. Finally we measure the temperature of a bulbs filament....
