Three capacitor each of capacitance `9 pF` are connected in series
What is the toal capacitance of the combination ?

Text Solution

Verified by Experts

Here `C_(1)=C_(2)=C_(3)=9 pF`
Voltage `V_(2)=120V`
Total capacitance in series combinations,
`(1)/(C_(S))=(1)/(C_(1))+(1)/(C_(2))+(1)/(C_(3))=(1)/(9)+(1)/(9)+(1)/(9)`
`(1)/(C_(S))=(3)/(9)`
`rArr C_(s)=3pF`
