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?

component : opposite of capacitor?

One owner. Only driven gently on Sundays. Sold to best offer. First to see will buy. Reward offered for safe return. Coming soon to a cinema near you. Available for a limited time only.
My waterbed broke this morning. Oh, I don't have a waterbed. Bugger.

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."Once upon a time we would obey in public, but in private we would be cynical; today, we announce cynicism, but in private we obey."

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 mapFor LAMS information and resources - http://www.perthstreetbikes.com/foru...thread-156358/
