Click on the black triangle by the Curve Fit icon on the graph toolbar and select Linear. 2.The horizontal error bars represent the +/- 0.1 mA uncertainty in the True Current which was achieved 3.The uncertainties in the slope and intercept arise from the spread of the data points but do not includethe uncertainty in the True Current. 4.Answer the first two Questions on the Conclusions page.Conclusions:Ohm’s Law1.How well does your data support Ohm’s Law? Explain fully!2.What is the physical meaning of the slope of the Linear Fit to the data on the Ohm’s Law graph. Hint: what are the units of the slope?

This can be improved substantially if a multi-meter is available. These will generally measure resistance +/- 1%. 1. Disconnect all the wires from the circuit board. 2. Use a multi-meter to measure the resistance of resistors R2, R3, & R4 on the circuit board. Enter the values in the Resistor Check Values table, replacing the nominal values in column 2. Theory Resistance: Using Equivalent Circuits (see Theory section above) and the values for the resistors from the Resistance Check Values table, calculate the equivalent resistance for each of the three circuits shown on the previous page. Enter the values in the Theory Resist. column of the Equivalent Circuits table below. Resistor Resistance (Ω) Circuit Theory Resist.
