Coupling and Decoupling | Applications | Capacitor Guide
Capacitors, like batteries, need time to charge and discharge. When used as decoupling capacitors, they oppose quick changes of voltage. If the input voltage suddenly drops, the capacitor provides the energy to keep the voltage stable. Similarly, if there is a voltage spike, the capacitor absorbs the excess energy.
Capacitive Voltage Divider Circuit as an AC Voltage Divider
Consider the two capacitors, C1 and C2 connected in series across an alternating supply of 10 volts.

Voltage divider circuits may be constructed from reactive components just as easily as they may be …

To AC-Couple or Not to AC-Couple? That Is the Question!
An AC-coupled output includes a series capacitor (Figure 1a), while a DC-coupled output does not (Figure 1b). A designer new to video output circuits may find such a choice confusing because adding a capacitor to the output path increases cost, requires space, and distorts the video signal. However, the choice may have already been made due to ...

Capacitors in Series
With capacitors in series, the charging current ( i C ) flowing through the capacitors is THE SAME for all capacitors as it only has one path to follow. Then, Capacitors in Series all have the same current flowing through them as i T = i 1 = i 2 = i 3 etc. Therefore each capacitor will store the same amount of electrical charge, Q on its plates regardless of its capacitance.

In analog circuits, a coupling capacitor is used to connect two circuits such that only the AC signal from the first circuit can pass through to the next while DC is blocked. This technique helps to isolate the DC bias settings of the two coupled circuits. Capacitive coupling is also known as AC coupling and the capacitor used for the purpose is also known as a DC-blocking capacitor. A coupling capacitor''s ability to prevent a DC load from interfering with an AC source is particula…
