Multiple Choice

A 5- $\mu \mathrm { F }$ , a $7 - \mu \mathrm { F }$ , and an unknown capacitor $C \mathrm { X }$ are connected in parallel between points $a$ and $b$ as shown in the figure. What do you know about the equivalent capacitance $C _ { a b }$ between $a$ and $b$ ? (There could be more than one correct choice.)

• A) \(5 \mu \mathrm { F } < C _ { a b } < 12 \mu \mathrm { F }\)
• B) \(C _ { a b } < 5 \mu \mathrm { F }\)
• C) \(C _ { a b } > 12 \mu \mathrm { F }\)
• D) \(C _ { a b } > C \mathrm { X }\)
• E) \(C _ { a b } < C _ { X }\)
