Unformatted text preview: Volts Time [s] .37 V max V max Difference is Tau WHAT DO WE DO WITH THAT DATA τ = R*C ? 200 700 800 1000 Resistance [Ohms] 40 120 200 220 Tau in micro seconds Regression line will have a slope with R^2 value. This is C! Important Notes • Do have plots for all five resistance values, assume 5% for the resistor box. These must be sketched in the graph paper provided in the lab manual. • Do have error for your Vmax and .63 Vmax values, use the scope deviation. • Do have error estimates for you Tau values! • Do have error estimates for your C values! • Use the min max method! • Lets look at an example...
