For this learning task, you will use the PhET DC circuit construction kit to simulate some series circuits as well as analyze series circuits using Kirchhoff's laws and Ohm's Law. Use the GRASP method to communicate your calculations and be sure to state your final answers using the correct number of significant digits. Complete the following tasks: 1. Create the following circuit using the simulator. Use an ammeter to measure and record the current flow through the battery and each light bulb. Use a voltmeter to measure and record voltage across the battery and each light bulb. 4 by PHET - University of Colorado 2. Complete a calculation to verify KVL for the circuit. 3. Predict the current flow through the battery if a 3rd light bulb were added to the circuit, Explain your prediction using Kirchhoff's Laws. 4. Add a 3rd light bulb to the circuit. Measure and record the current flow through the battery. Did your prediction match the result? 5. Create a schematic diagram of a circuit that has a battery supplying 23 V to three resistors (R, = 158, R2 = 449 and Rs = 259) connected in series. 6. Complete an analysis, using Kirchhoff's laws and Ohm's Law, to predict all V and / in the circuit. 7. Create the circuit from the schematic diagram you created in question 5. Measure and record all V and / and compare to your calculated values 8. Complete a calculation to determine the equivalent series resistance that could replace the resistors in the schematic diagram you created in question 5
