Lab 7 Ohm’s law<\/p>\n
Associated videos: Ohm’ s law and How to connect the six resistors<\/p>\n
Goal<\/p>\n
To measure voltage across resistors in series. To use Ohm’s law.<\/p>\n
Activity<\/p>\n
part 1<\/p>\n
Build the connections with one resistor only. Use the 1kOhm resistor. Use 3.3 Volts.<\/p>\n
Measure the voltage across the resistor with the multimeter.<\/p>\n
Kit voltage value:<\/p>\n
Measured value:<\/p>\n
% difference:<\/p>\n
part 2<\/p>\n
a) Connect all resistors in series. Built the connections with 6 resistors (use 1kOhm, 2kOhm, 5.1kOhm combinations). Measure the voltages across each one of them, and across two or three of them.<\/p>\n
Since the resistors are all in series, the current drawn from the power source is the same for all of them. <\/p>\n
b) On the usual spreadsheet, build a table similar to the table below with the resistance and the voltages. Measure in total at least 9 data points. <\/p>\n
c) Use your data to build a chart with Voltages vs. Resistances. <\/p>\n
d) Build the line of best fit. What is the slope equal to? Ask to show the equation.<\/p>\n
e) On the spreadsheet, include a row with the calculations to find the equivalent resistance for the six resistors in series and the total current.<\/p>\n
f) Compare the value of the total current found on part (e) with the slope from the plot. %error.<\/p>\n","protected":false},"excerpt":{"rendered":"
