question 9

Multiple Choice

Use the formula $\frac { 1 } { C } = \frac { 1 } { C _ { 1 } } + \frac { 1 } { C _ { 2 } } + \frac { 1 } { C _ { 3 } }$ . Given $C = 1.75 \times 10 ^ { - 12 } \mathrm {~F}$ , $C _ { 2 } = 8.45 \times 10 ^ { - 12 } \mathrm {~F}$ and $C _ { 3 } = 6.35 \times 10 ^ { - 12 } \mathrm {~F}$ Find $C _ { 1 }$ .

• A) \(C _ { 1 } = 2.78 \times 10 ^ { - 12 } \quad F\)
• B) \(C _ { 1 } = 2.88 \times 10 ^ { - 12 } \quad F\)
• C) \(C _ { 1 } = 4.28 \times 10 ^ { - 12 } \quad F\)
• D) \(C _ { 1 } = 3.68 \times 10 ^ { - 12 } \quad F\)
• E) \(C _ { 1 } = 3.38 \times 10 ^ { - 12 } \quad F\)
