Step-by-step solution
The equivalent capacitance of C₁ and C₂ in series is C₁₂ = 6 3 6 + 3 = 2 F . This combination is in parallel with C₃ = 2 F , so the equivalent capacitance of the parallel block is C₁₂₃ = 2 + 2 = 4 F . The parallel block is in series with C₄ = 4 F . The total equivalent capacitance of the circuit is C_ eq = 4 4 4 + 4 = 2 F . This matches (A) with (II). The total charge drawn from the battery is Q_ total = C_ eq V = 2 F 24 V = 48 C . Since C₄ is in series with the rest of the circuit, the charge on C₄ is the total ch
