Module 7: Electricity - Electric Charge and Current Topic 5: Combination Circuits Application Procedure: Open the Circuit Construction Kit from the PhET web site (also found in the "Content" tab of this topic). Select "Intro" and complete the tasks below. CIRCUIT #1 1. Put three resistors and a battery on the work area. Change each of the resistances to the values in the table below. Use a battery voltage of 12 volts. Build the circuit given in the figure below by connecting each component with wires. Calculations Resistor Individual Current Voltage resistance (ohms) (amps) (Volts) 10 20 3 30 Totals: 2. Use the procedures learned in this topic to calculate: (Show your work for each problem below and record your results in the table above). You can verify your answers using the voltmeters and ammeters available. a. The resistance in the parallel portion of the circuit. b. The total resistance of the circuit. . The total current delivered by the battery. d. The current and voltage for resistor 1. e. The voltage for the entire parallel portion of the circuit. f. The voltage and current for resistor 2. g. The voltage and current for resistor 3. think plex3. Provide evidence that your table information is reasonable. Before you dismantle your experiment, take a screenshot of your circuit and insert it into this document. (Refer to the Developmental Module for instructions on how to take screenshots). 4. Briefly explain how Kirchoff's Loop Rule and Kirchoff's Junction Rule justify your results. CIRCUIT #2 5. Once again, put three resistors and a battery on the work area. Change each of the resistances to the values in the table below. Use a battery voltage of 12 volts. Build the circuit given in the figure below by connecting each component with wires.
