How current "passes" through a capacitor
A voltage or current source that produces a constant voltage, such as a battery. In a DC circuit (meaning #1), a capacitor acts like an open circuit. No current flows through it. If your circuit has a charging capacitor, it''s not a DC circuit, because the capacitor voltage and current are changing over time.
Using a capacitor to sustain battery life
To add another wrinkle, don''t forget that every MCU vendor requires one or more decoupling capacitors, even when running from a battery. Generally they want one of about 10 uF. Be sure to use a low-leakage part, and factor that into your battery capacity calculations.
Capacitor Basics: How do Capacitors Work?
Reversed voltages. Some capacitors do not care about voltage polarity but some, particularly electrolytic capacitors, cannot accept reversed voltages or else they''ll explode. Explode may be a strong word, they usually just poof a little and stop working. Lifespan. Over time, capacitors age and their capacitance drops.
capacitor
The amount of current depends on the capacity of the capacitor and the frequency of the AC. Also see this relevant discussion. Why isn''t this standard in all bulbs? Because it would waste energy. Unless you need some current to pass constantly to power this special kind of switch you shouldn''t install such a capacitor with the bulb.
When To Add Capacitors to Your Car Subwoofer System
