    Will ESR of capacitor affect charging time?

    I have three capacitors put in series, each has 1F 5.5V, connected to a circuit with a resistor 33 ohm and 13V supply. Will the value of ESR (Equivalent Series Resistance) affect the time constant RC? That means R = 33 only or, if each capacitor has 30 ohm ESR, value R would equal
    33 + 3 * 30 ?

    Your help will be appreciated. Thanks!

      Re: Will ESR of capacitor affect charging time?

      the lower the esr, the faster a cap will both charge, and discharge.
      i dont know how you calculate it because it will be related the the current capacity of the cap (ripple current)

          ASUS X54H laptop thinks it's always charging even with charger unplugged
          by flat-earther
          The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.

          Windows also shows ''Plugged in'' when charger is not connected.

          This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
          Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
          If I let battery run out and say it has 3% Windows will...

          desoldered capacitor is self charging until 0.6 voltage.
          by chth96
          I have an 21 inch CRT TV which is not able to power on.
          I disassembled 21 inch CRT TV and measured voltage of main filter capacitor(Samhwa HC 400WV 220uF) in the circuit.
          It shows 270V on my DMM.

          So I discharged this main filter capactior completely and detached circuit board from cathode-ray tube.
          Then I desoldered this main filter capacitor from circuit board.
          But I noticed that this desoldered large capacitor(Samhwa HC 400WV 220uF) is slowly charged by itself until it reached 0.6V

          I measured its ESR value with MESR-100 and it shows 0.1 ohm,judging...

          HP Probook 470 G4 - Power and Charging Problem
          by Scoff
          Looking for some help with this one if anybody can assist please? I have an HP Probook 470 G4 Laptop which recently started to intermittently failing to turn on, with intermittent white LED light(charging LED) by the charging port when it should have been charging and showing an orange LED instead. Definitely some sort of gradual failure. Now the laptop fails to power on at all, no charging LED, no Power Button LED either - seemingly dead.
          Stripped down to the bare motherboard. The original HP battery, when disconnected from the motherboard, is reading 0.00v - possibly some sort of protection...

          RTX 3080 FE Identifying capacitor
          by Prolog
          Hi people, I hope this is the correct spot to post this, I'm new to the forum.

          I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.

          I hope these photos make it clear which component I am referring to:
          (yes, the soldering is a bit botched from removing the blown one, I know)

          I have found the board schematic (attached), but there does not seem to be a boardview available. I have never...

          Adding a clock battery to action camera to retain date&time when changing batteries Campark X25
          by flat-earther
          I have a cheap action camera with an annoying trait, every time I change batteries the date & time gets reset and I have to set it again.

          To solve this problem I want to add a small internal battery inside it which will keep supplying power to the camera for a while while I change batteries so the date & time is retained.

          I have opened the camera and I think there is enough room to add something inside to accomplish this:

          The camera is powered by a 3.7V nominal single cell lithium ion battery.
          So I need to connect another battery in...
