What are some reasons to connect capacitors in series?
Capacitors have a maximum voltage they can take before the dielectric (or vacuum) inside of them breaks down and starts conducting. Thus, if you need to have a capacitor in a high voltage circuit it may be necessary, or just more convenient, to place them in series.
Why is the capacitor short-circuited in this example?
Any element for which terminals are connected by a conductor, as the capacitor in the figure, is said to be shorted. By having their shorted terminals, the voltage thereof is zero (more precisely, the potential difference …

Why does voltage lag current in a pure ac capacitor circuit
well in the case of DC. the capacitor charge cruve with DC is inverse exponential. But it does show what happens when the voltage rises and current decreases. apply an alternating voltage (AC) for a repeating change and then things like as you expect with AC.
The Fundamentals of Capacitors in AC Circuits
Capacitors in Series. When two capacitors are placed in series, the effect is as if the distance between the outside plates were increased and the capacity is therefore decreased. On an alternating current supply, this effectively increases the opposition to a current flow in a similar fashion to that of resistors placed in series:
Capacitors in series | Applications | Capacitor Guide
When capacitors are connected in series and a voltage is applied across this connection, the voltages across each capacitor are generally not equal, but depend on the capacitance values. More precisely, the ratio of the voltages across individual capacitors is the inverse of the ratio of the capacitance values of each individual capacitor in the series.
