How would I be able to produce a circuit that produces a very high current at a very low voltage? Would it be considered a reverse Tesla coil?
Welcome to the PF.How would I be able to produce a circuit that produces a very high current at a very low voltage? Would it be considered a reverse Tesla coil?
Welcome to the PF.
Are you wanting AC or DC high current capability? What level of current are you asking for? Can you say what the application is?
Woo doggies! That's a lot of amps. How long do you need to sustain this level of DC current? How close is the nearest power substation?
Your Profile page says you are in Undergrad right now. Do you have an advisor for this research work? What is your budget for creating this facility?
What is a very low voltage? Is it 20uV, 1V or 50V ?How would I be able to produce a circuit that produces a very high current at a very low voltage?
200 million amps
Seems like you've used those numbers in previous posts on another forum...I believe for 0.18 seconds
Me too. Great for car wiring - trailer lights, repairs,Heck. I still use mine.
The energy involved in 200Mega-amp with a 1 volt drop for 0.2 seconds is equivalent to 40kg of TNT.
Yes I do have an advisor and we have a budget of 250k.
When a welding level regulated current passes through a poor weld, there is a change in the flow path of the current that can be detected by magnetic powder, or mapped with hall effect sensors. That technique of crack detection has been used for many years.I may not recall correctly, but my mind suddenly pictured 0.85V and 100A.
Thanks !but the main point can be seen here.
Another useful repurposing is to supply the soldering gun with a variac, add an ammeter, and use it as an adjustable high current source to check whether motor starter thermal overload relays trip at their rated values. It can also be used to check the calibration of, and set up AC current to 4-20 ma/0-10V signal conditioners.Me too. Great for car wiring - trailer lights, repairs,
and if you replace the tip with a coil of #12 solid you have a demagnetizer for hand tools tape heads and the like. . Worked great when an unshielded subwoofer underneath my Sony Triniton turned that corner of the screen purple. (today's flatscreens seem unaffected )
Will pick one up for you.
Waitaminnit .... how did my soldering gun end up into that junk shop?Current density is the limiting factor.
For more reasonable currents in a household experimental environment ,
buy a secondhand soldering gun to take apart and play with.

low voltage high current out of those two stubs.
Junk shops are full of them, around here they go for five bucks..
Big boy stator!A bit of an advertising (sorry), but the main point can be seen here.
Let's do total cross-sectional current:DC high current capability, 200 million amps, research study
