Find the total capacitance of the combination of capacitors shown in the figure below.

Answer 1

if C1 and C2 are the individual capacitor that re connected in series,
then their resultant capaciatnce 1/Cnet = 1/C1+1/C2 or Cnet = C1C2/(C1+C2)

if c1 and C2 are connected in parallel, then their effective capacitancen is Cnet = C1+C2

also in sereis combination same amount of charge passes through each of the capacitiors

and in parallel combination, same PD (voltage) exists across each of the capacitor

so here

from right to left,

0.75 and 15 are in parallel -------> 0.75 + 15 = 15.75 uF

this 15.75 uF is in series with 3.25uF ------> (3.25* 15.75)/ (3.25+15.75)= 2.7 uF

left most 5.15 anf 3.55 are in series = 5.25* 3.55/(5.25 + 3.55) = 2.11 uF

finally 2.11uF , 2.7uF and 5.25 are in parallel

Cnet = 2.11 + 2.7 + 5.25 = 10.06 uF
