  • component : opposite of capacitor?

    I am after an electrical component which allows current to flow, but after x amount of current flows, it will prevent anymore current from flowing. anyone know the name of such a component?

    A capacitor wired in series instead of in parallel?

    Need a little more information d0od - what's the application, what's "resetting" this thing, etc...

              if you install the wires on a slight slope, it will slow the current flow a bit.

                  If you were talking voltage not current, I would say a Zenner Doide.

                  More info?

                      But according to that picture, he only got 1 Amp of charge.

                        haha

                        resistor : nope : it limits the amount of current but doesn't stop it.
                        regulator : regulates voltage and will only stop current flow if voltage reaches a predetermined value
                        fuse : limits the amount of current (I'm talking about turning the current flow of after a period of time)

                        having the wires on a slope might be the best solution!!

                          Current flow off after a certain period of time? Capacitor in parallel with a resistor between the base and emitter of an N type IGBT. Pulse the gate high to start the current flow and charge the cap. Current can go through whatever it is you're feeding, through the collector and out to the emitter of the IGBT (emitter tied to ground). It will keep doing this until the resistor has discharged the capacitor to below the hold-on gate-emitter voltage, when the IGBT will shut down.

                          Could probably do it with an N-channel FET or a darlington NPN-PNP BJT setup too.

                            oh god *fish, I just had flashbacks to circuit design at uni in the early/mid 90's. I understood just enough of that to scare myself.

                            Now I shall go and express these feelings in a Karnaugh map
