Voltage Division Rule basically tells us about the voltage drop across individual resistance in a series connected resistance.This rule is applicable for AC and DC circuit. However, while applying this rule in AC circuit, impedance value should be considered instead of resistance value due to obvious reason.
What is Kirchhoff''s Voltage Law (KVL)? The principle known as Kirchhoff''s Voltage Law (discovered in 1847 by Gustav R. Kirchhoff, a German physicist) can be stated as such: "The algebraic sum of all voltages in a loop must equal zero" By algebraic, I mean accounting for signs (polarities) as well as magnitudes. ...

Capacitive voltage dividers are circuits, which employ capacitors in series with an alternating current (AC) power supply to produce a voltage drop across each capacitor.
