SUMMARY
The voltage across capacitor C2 in the given circuit is determined to be 20V, despite the initial calculation yielding 15V. The user correctly identified that capacitors C2 and C3 form a voltage divider across a 30V supply. Since C2 and C3 have equal capacitance, they equally share the total voltage, resulting in 20V across each capacitor. The initial conditions, such as charges on C1, were not necessary for this calculation.
