Using a 1-mF capacitor,a 2-mF capacitor,and a 3-mF capacitor,which of the following capacitances cannot be made by a combination that uses all three? (Hint: At most only 2 combinations must be considered to determine the correct answer).
A)6 mF
B)6/11 mF
C)11/3 mF
D)5/11 mF

The total capacitance of capacitors in series is given by 1/C_total = 1/C1 + 1/C2 + 1/C3, and in parallel by C_total = C1 + C2 + C3. By calculating these combinations, 5/11 mF cannot be achieved using all three capacitors.
