Capacitor charged indicator light

simple led indicator to show when capacitor is charged

Unless your charging current is very small, 4700uF will charge to >28V in next to no time. I''m curious as to why you want to use a LED to indicate full charge?

Design Note 303: Photoflash Capacitor Charger Has Fast

Figure 1a shows a typical LT3420 circuit that can charge a 220μF photoflash capacitor to 320V in 3.5 seconds from a 5V input. Figure 1b shows the charge time as a function of battery voltage.

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

Led charge indicator for small supercapacitor (1F x 5.5v)

I have been playing around with a supercapacitor, 1F rated 5.5V. I charge it mostly through USB, which usually takes a couple of minutes to reach a good amount of

Capacitor charged/full indicator

I''m charging a high voltage capacitor to 200v. I''m looking for a way to turn on an LED when the cap isn''t taking any more power or when it has reached the full 200v. This will

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

Indicator LED directly to AC mains. Which method would you use?

The capacitor will charge up to the peak voltage and the LED will be out. $endgroup$ – Jack Creasey. Commented Feb 23, 2018 at 0:08 | Show 3 more comments.
