It's just that i've never properly sorted this confusion of mind, so i would like to sort it out so it 2 different capacitors are in series with a resistor: (let's say 0.15F, 0.45F, 150M ohm) 1. both current and voltage drops exponentially 2. capacitance on capacitors remain same over time? 2. the charge on capacitors is same over time? because Current decreases, and Time increases, does that mean Charge (Q=I*T) is unchanged 3. at t=0 charge on cap 1 = charge on cap 2? Since they're in series, current should be same, therefore charge is same? But Q=CV, and capacitance is different thankyou.
