Expert Solution
Step 1

Given,

Vab=10 V

When two capacitors are connected in parallel

 Ceq=C1+C2When two capacitors are connected in seriesCeq=11C1+1C2

The 28μF and 14μF are connected in series.

1C1=128+114=28+1428×14=0.107C1=10.107=9.33μF

C1 and the other 3 μF are connected in parallel.

C2=9.33+3+3=15.33 μF
