Question

A network of four capacitors of 6 μF each is connected to a 240 V supply. Determine the charge on each capacitor.

 

Solution

C2,C2 and C3 are in series

`:.1/C_s=1/C_1+1/C_2+1/C_3`

`=1/(6xx10^(-6))+1/(6xx10^(-6))+1/(6xx10^(-6))`

`1/C_s=3/(6xx10^(-6))`

∴ Cs = 2x10-6 F

Cs and C4 are parallel

∴ equivalent resistance

C = Cp = Cs + C4

= 2x10-6 + 6x10-6

C = 8x10-6

∴v = v1+ v2+ v3

240 = 3v1  {v1=v2=v3}

∴ v1  80 volt

Also charge on C1,C2 ,C3 are same.

Q1 = Q2 = Q3 = Q

Q = C1v1

= 6x10-6 x 80

Q = 480x10-6C and Q4 = 6x10-6x 240= 1440μC

  Is there an error in this question or solution?
