First, we are going to nd theoretical values using the circuits shown below. Copy the circuits to your lab report, and answer the questions. Part A: Capacitors in Series 2. 1hree capacitors (C1 : 1 x 1013 F, C2 : 2 x 1'013 F and C3 = 3 x 1013 F) are connected in series as shown in Figure 1. The battery voltage is 1.5 V. Internal resistance of the batte I iii 3 | 3. Calculate the following values. Show complete work. A) Calculate the equivalent capacitance of the circuit. B} Calculate the total charge (1 stored in the three capacitors (this is the same charge in a capacitor with the equivalent capacitance calculated above). C) Calculate the voltage across C1, voltage across C2, and voltage across C3. E E Spacing D) Do above voltage values add up to the voltage provided by the battery? Values calculated in steps A-D are theoretical values for capacitors in series. Now, we build the same circuit using a PhET simulation. Part B: Capacitors in Parallel 4. Three capacitors (C1 = 1 x 10-13 F, C2 = 2 x 10-13 F and C3 = 3 x 10-13 F) are connected in parallel as shown in Figure 2. The battery voltage is 1.5 V. Internal resistance of the battery and wire resistance are negligible. C3 C2 C1 1.5 V Figure 2 5. Calculate the following values. Show complete work. E) Calculate the equivalent capacitance of the circuit.

G) Calculate the charge in C1, charge in C2, and charge in C3.View Acrobat 9 Tell me AaBchDdEe AaBchDdEe Normal No Spacing H) 00 above charge values in step (G) values add up to the total charge calculated in step (F)? Values calculated in steps E-G are theoretical values for capacitors in parallel. Part C: Capacitors in both Series 8: Parallel 6. Three capacitors (C1 = 1 x 1015 F, C2 = 2 x 1013 F and C3 = 3 x 1043 F) are connected as shown in Figure 3. The battery voltage is 1.5 V. Internal resistance of the battery and wire resistance are negligible. 7. Calculate the equivalent capacitance of the circuit. Show complete work. This is the theoretical value for the capacitor combination. Simulated Values: 8. Now we are going to build the circuits shown in Figure 1, Figure 2 and Figure 3 using a Ehjlj'simulation.

Spend a few minutes exploring the functionalities of the different tabs/panels. 10.60 to Multiple Capacitors tab. Check \"Plate Charges\15. Now build the circuit shown in Figure 3 (capacitors in both series & parallel) by using "2 in Parallel + 1 in Series" option. Change capacitance values according to C1, C2 and C3 values given in step 6, and set battery voltage to 1.5 V. Complete Table 3 using the values shown in the simulation. 16. Take a screenshot of the circuit and copy it to your lab report. Theoretical Simulated % Error Values Values Equivalent Capacitance (F) Table 3: Capacitors in both Series & Parallel 17.In each circuit, do your theoretical values (calculated values) agree with simulated values? If not, explain possible errors in discussion section of the report. Remember that if % error is greater than 10%, theoretical and simulated values do not agree. Late labs will not be accepted, so don't wait until the last minute. I recommend trying to complete them Monday-Thursday so that you can ask me for help if needed, as I won't be available on the weekends, and also so that you have time to resolve any computer/technical issues that you might encounter when trying to submit your assignment. 3 206
