Question 278: Electrostats & Capacitance

Question

Seven capacitors, each of capacitance 2 $$\mu $$F, are to be connected in a configuration to obtain an effective capacitance of $$\left( {{6 \over {13}}} \right)\mu F.$$ Which of the combinations, shown in figures below, will achieve the desired value

Accepted Answer

C
eq
= $${6 \over {13}}$$$$\mu $$F
Therefore three capacitors most be in parallel to get 6 in
$${1 \over {{C_{eq}}}} = {1 \over {3C}} + {1 \over C} + {1 \over C} + {1 \over C} + {1 \over C}$$
C
eq
= $${{3C} \over {13}}$$ = $${6 \over {13}}$$$$\mu $$F
