Customer ServiceCombining capacitors in series reduces the total capacitance, and isn''t very common, but what are some possible uses for it? It shouldn''t be used to increase the voltage rating, for instance, since you can''t guarantee that the middle will be at half the DC voltage of the total, without using bleeder resistors.

Customer ServiceThe combination of a resistor and capacitor connected in series to an AC source is called a series RC circuit. Figure 1 shows a resistor and pure or ideal capacitor connected in series with an AC voltage source. The current flow in the circuit causes voltage drops to be produced across the capacitor and the resistor.

Customer ServiceYou can either "cut" the original resistor along its length which is equivalent to smaller value resistors in series or you can "cut" the original into "slices" (like from a very tall cake) along its length which is larger value resistors in parallel.

Customer ServiceThe capacitor and resistor are connected in parallel so I think that the resistor will draw a current I=VR but the capacitor is an ideal one therefore has no resistance and therefore draws an infinite amount of current which eventually stops when the capacitor is completely charged so overall. There is a subtle problem here with the logic.

Customer ServiceIn a series RC circuit, the resistor and the capacitor are connected in a series configuration, meaning that the current flowing through the circuit passes through both components sequentially. The resistor resists the flow of current, while the capacitor stores energy in the form of an electric field. A series circuit consisting of capacitance (C) and resistance (R)
Customer ServiceWith series connected resistors, the sum of all the voltage drops across the series circuit will be equal to the applied voltage VS ( Kirchhoff’s Voltage Law ) and this is also true about capacitors in series. With series connected capacitors, the capacitive reactance of the capacitor acts as an impedance due to the frequency of the supply.
In some physics contexts, a resistor is connected in series with a capacitor to allow for quicker charging and a smaller time constant. However, the exact reason for this and how it works is a more complex topic. It's not always the case that a resistor must be connected in series with a capacitor; it depends on the specific application and design considerations. Your lecturer's statement may be correct in certain situations, but it's essential to understand the underlying principles before making assumptions.
Now we will combine the two components together in series form and investigate the effects. Series capacitor circuit: voltage lags current by 0° to 90°. The resistor will offer 5 Ω of resistance to AC current regardless of frequency, while the capacitor will offer 26.5258 Ω of reactance to AC current at 60 Hz.
A resistor can be connected in parallel to a capacitor without affecting the charging time. There's nothing wrong with this configuration. However, charging of a capacitor takes infinite time if a resistor is connected in series. The time constant for an RC circuit is RC. So, the charging time would actually increase if a resistor is connected in series.
If a resistor is connected in series with the capacitor forming an RC circuit, the capacitor will charge up gradually through the resistor until the voltage across it reaches that of the supply voltage. The time required for the capacitor to be fully charge is equivalent to about 5 time constants or 5T.
Connecting them in series increases the voltage capability (add voltage limits of all caps in series). To have robustness against short circuit specially ceramic capacitors that are connected to power lines. If capacitor shorts, it can burnt PCB trace or worst it may cause fire.
