AP 10006 Test (Total 100 Marks) Question 1(26.28) Consider the following figure. (a) Find the equivalent capacitance between points a and b for the group of capacitors connected as shown in the figure above. Take C1 = 6.00 µF, C2 = 3.0 µF, and C3 = 2.00 µF. (15 marks) (b) What charge is stored on C3 if the potential difference between points a and b is 100.0 V? (15 marks) Answers (a) C1 and C2 in series = 2uF Cupper = 2uF + 2uF + 2uF = 6uF Clower = 3uF + 3uF = 6uF Cequ = 3uF (b) Qupper = Qequ = Cequ V = 3uF100V = 300uC Vupper = Qupper/Cupper = 300uC/6uF = 50V Charge stored in C3 = 2uF50V = 100uC (15 marks) (15 marks) Question 2 (27.53) A charge Q is placed on a capacitor of capacitance C. The capacitor is connected into the circuit as shown in the figure below, with an open switch, a resistor, and an initially uncharged capacitor of capacitance 4C.
Connect the dots on the line. Print a copy of the graph window and data window. Do the extension. Data: volume (mL) Pressure(atm) Constant, k (PxV) 5.0 2.0 10.0 7.5 1.3 9.75 10.0 1.0 10.0 12.5 0.8 10.0 15.0 0.7 10.5 17.5 0.6 10.5 20.0 0.5 10.0 k=PV ex. 10.0= 5.0x 2.0 Conclusion: When the volume was doubled from 5.0 mL to 10.0 mL the pressure was halved from 2.0 atm to 1.0 atm.
