Calculations Find the combined resistance of R₁ and R₂ in series and in parallel by the volt-ammeter method using the data in tables 1-4. Calculate the combined resistance of R₁ and R₂ in series and in parallel using the Digital Multimeter value (accepted truth value) and the equations: R = R₁ + R₂ and R = R₁ R₂ R₁+R₂ Calculate the percent difference for each case and write your conclusion on the experiment.
