LED still glowing with a capacitor in series
$begingroup$ @Willis Electrolytic caps are not specified to operate conductively with reverse voltage applied, so there us no definitely safe current. A rule of thumb is that typical caps are not destroyed by applying line-frequency AC if it does not exceed around 3% of the rated DC voltage.

Sizing Capacitors for a dimmable LED light
Hi, While i understand the general theory behind how a capacitor works I am not clear on how to calculate the amount of charge a specific capacitor can hold. For example I have a Strip of 5v Neopixels, that the manufacturer says draws 7.5Watts When i cut the power to the strip rather than turning off instantly I would like it to fade out over a 10 second period. Same
Choosing the right capacitor for LED designs
This article explains the root of the problem and makes recommendations for ensuring ceramic capacitors do not cause lifetime problems for LED lighting products. Typical conditions in LED circuitry. A typical LED lighting circuit is shown in figure 1. For C1, C2, and C3 safety recognised capacitors should be selected that are rated AC 250Vrms.
How to Use a Charged Capacitor to Light an LED
When the button is pressed down, closing the circuit, the battery does two jobs: it charges the capacitor up with voltage and it gives power to the LED, lighting it. Once the battery is on for enough time for the capacitor to be fully charged up to 9 volts, the capacitor cannot retain any more charge. This happens in a matter of seconds.
what does the capacitor really do? It collects stores
For example, consider a circuit that uses a capacitor to smooth out a pulsating DC voltage. The capacitor is connected in parallel with a load, such as a light bulb. When the voltage across the capacitor is zero, it will start charging up

Electrolytic capacitors can fail by discharging too much current or by running out of electrolyte and being unable to hold a charge. Non-electrolytic capacitors most
Installing a capacitor in a light bulb? : r/electrical
For those asking why a capacitor, the OP is installing smart switches in a place he does not have a neutral. Typically the neutral requirement is so the smart switch has continuous power, I''m assuming from what I''ve found online that
pwm
$begingroup$ I had some of the bulbs removed from the circuit(s) in the car when testing, and that''s when I observed the blinking (low frequency). After I fitted all the bulbs, the dimming function worked as expected in almost all of the lighting circuits. Some combination of the extra circuit resistance or logic in the lighting controller must have been satisfied and

Capacitors, when failing, often exhibit distinct physical signs that can be spotted carefully. Here, we expand on the key visual indicators of capacitor failure.
Understanding Capacitors: The Misunderstood, Underappreciated Capacitor
Generally speaking, the bigger the capacitor the darker the tone, and the smaller the capacitor the brighter the tone. A capacitor''s value, or capacitance, can give you an idea of just how it will affect tone, from slightly warm all the way to dark. Here are some guidelines: A Quick Reference for Capacitor Values Capacitance (in UNITS)
Am I supposed to put capacitor on lamp when using wifi smart light
I think the provided capacitor is only for LED lights to prevent them from flickering. That switch burned out yesterday when my mother pressed the touch sensor to turn the lights on. I do not think this is from the fact that there was no capacitor installed, but maybe a faulty switch, since those are Chinese and in the range of 25 dollars/piece.

Capacitor circuits with light bulb
When one places a capacitor in a circuit containing a light bulb and a battery, the capacitor will initially charge up, and as this charging up is happening, there will be a nonzero current in the circuit, so the light bulb will light up. However, the capacitor will eventually be fully charged at which point the potential between its plates
Smart switch without neutral requires capacitor. How to connect?)
All the other light switches I have replaced with Kasa TP-link switches have been no problem. Then I ran into this one that operates the garage light. If wired like a single-pole switch, the Kasa switch makes a clicking sound but will not control the garage light. Any ideas what I''m up against here?

6 FAQs about [What to do if the red light of the capacitor does not light up]
How do you know if a capacitor is not working properly?
Diminished electrical performance is a common sign that a capacitor is not working properly. This can manifest in various ways, such as reduced power output, flickering lights, or unexpected device shutdowns.
Can a capacitor fail without any visible signs?
Yes, it is possible for a capacitor to fail without any visible signs. Sometimes, a capacitor may have internal issues or damage that is not immediately apparent from its exterior.
What happens if a capacitor is leaking?
Leaking capacitors, on the other hand, release electrolyte fluid, which is a strong indicator that the component is faulty. This fluid can corrode nearby components and cause further damage to the circuit board. Any signs of liquid or residue around the capacitor should not be ignored.
What causes a non-electrolytic capacitor to fail?
Electrolytic capacitors can fail by discharging too much current or by running out of electrolyte and being unable to hold a charge. Non-electrolytic capacitors most often fail by leaking their stored charge.
How do you know if a capacitor is leaking?
Identification: Electrolytic capacitors can leak their internal electrolyte when they fail. This leakage can appear as a wet or crusty residue around the base of the capacitor or seeping from the top. Consequences: The leaked electrolyte can be corrosive and may damage the circuit board or other components it comes into contact with.
