Resistor Combinations Lab PHYS 421 Lab Group Members: You will be using this phet simulation: https://phet.colorado.edu/sims/html/circuit-construction- kit-dc/latest/circuit-construction-kit-dc_en.html We will be working with the simulation on the "Lab tab. Preliminaries: The values you calculate here are your theoretical values. 1. Find the current through the emf and the current and voltage in each resistor. 12 V R = 189 w R =90 2. Find the current through the emf and the current and voltage in each resistor. 12 V R = 182 ww R = 9 www w R = 60 R = 60 3. Find the current through the emf and the current and voltage in each resistor. 4. Find the current through the emf and the current and voltage in each resistor. R = 1892 12 V R =90 R = 60 w-w w R = 1892 12 V R = 60 ww ww R =90 Experiment 1. Use the simulation to build the circuit in step 1 of the preliminaries. Measure the current in the emf and the current and voltage in each resistor. Record your values. These are your experimental values. Find a percent difference between your experimental and theoretical values. percent difference = experimental - theoretical theoretical 100% 2. Use the simulation to build the circuit in step 2 of the preliminaries. Measure the current in the emf and the current and voltage in each resistor. Record your values. These are your experimental values. Find a percent difference between your experimental and theoretical values. 3. Use the simulation to build the circuit in step 3 of the preliminaries. Measure the current in the emf and the current and voltage in each resistor. Record your values. These are your experimental values. Find a percent difference between your experimental and theoretical values. 4. Use the simulation to build the circuit in step 4 of the preliminaries. Measure the current in the emf and the current and voltage in each resistor. Record your values. These are your experimental values. Find a percent difference between your experimental and theoretical values.
