Question 646: Electrostats & Capacitance

Question

The effective capacitances of two capacitors are 3 $$\mu$$F and 16 $$\mu$$F, when they are connected in series and parallel respectively. The capacitance of two capacitors are :

Accepted Answer

Here, $${1 \over {{C_1}}} + {1 \over {{C_2}}} = {1 \over 3}$$ (Series combination)
While, $${C_1} + {C_2} = 16$$ (Parallel combination)
Solving the above equations we get
$${C_1} = 12\,\mu F$$ and $${C_2} = 4\,\mu F$$

Answer

1.2 $$\mu$$F, 1.8 $$\mu$$F

Answer

10 $$\mu$$F, 6 $$\mu$$F

Answer

8 $$\mu$$F, 8 $$\mu$$F

Answer

12 $$\mu$$F, 4 $$\mu$$F
