Question 258: Electrostats & Capacitance

Question

Figure shows charge (q) versus voltage (V)
graph for series and parallel combination of two
given capacitors. The capacitances are :

Accepted Answer

As q = CV
Hence slope of graph will give capacitance. Slope will be more in parallel combination.
Hence capacitance in parallel should be 50 $$\mu $$F and in series combination must be 8 $$\mu $$F.
Only in option 40 $$\mu $$f and 10 $$\mu $$F.
C
parallel
= 40 + 10 = 50 $$\mu $$F
C
series
= $${{40 	imes 10} \over {40 + 10}} = 8\mu F$$

Answer

40 $$\mu $$F and 10 $$\mu $$F

Answer

60 $$\mu $$F and 40 $$\mu $$F

Answer

20 $$\mu $$F and 30 $$\mu $$F

Answer

50 $$\mu $$F and 30 $$\mu $$F
