Q1. Capacitor and voltage in series and parallel
Ans. 
Capacitors in series add reciprocally, in parallel add directly. Voltage in series is the sum, in parallel is the same.
• Capacitors in series: 1/Ctotal = 1/C1 + 1/C2

• Capacitors in parallel: Ctotal = C1 + C2

• Voltage in series: Vtotal = V1 + V2

• Voltage in parallel: Vtotal = V1 = V2
