question 65

Multiple Choice

A 5-µF, a 7-µF, and an unknown capacitor C_X are connected in parallel between points a and b as shown in the figure. What do you know about the equivalent capacitance C_ab between a and b? (There could be more than one correct choice.)

• A) C_ab > 12 µF
• B) C_ab > C_X
• C) 5 µF < C_ab < 12 µF
• D) C_ab < 5 µF
• E) C_ab < C_X
