Amplified Circuit

02/17/2011 4:44 PM

What are the components necessary and what order would I arrange them to increase 12v.a.c. to 110 ac @ 60hz

What needs increasing?

[It's got to be these glasses - either that or Anno Domini....]

A transformer is all that is needed as others have stated - with some overload protection devices, of course.

A "transformer" with a 10:1 turns ration would give you 120VAC from 12VAC. If you are trying to operate something for the US you should shoot for 120VAC, 110VAC went out with the dinosaurs.

But how much power do you need at 120VAC? If it's anything more than a few amps your 120VAC source had better be very large, because the same ratio holds, but in the inverse. So for every 1 amp you need at the 120V side, you will need 10A capacity on the 12V side.

Maybe you could describe what you are trying to do rather than just tease us with a small glimpse of the puzzle?

Thank you for taking the time to respond. The project is six cells, three zinc posts pounded in the ground and three copper from which I show 12.6 volts which are holding steady and running through a coil, hence the assumption that the current isn't d.c. My intention is to run the pump and lights to my fountain/fish pond. I have looked at many different schematics and in the end I've got to swallow my pride and admit that I dont understand the building of circuits so I was hoping someone could advise me in a fashion that would enable me to go to a supply store and ask for specific components and then come home and connect the dots so to speak. Am I being realistic? Thanks again for your time.

In this later description, the current is DC, so you would need an inverter to get AC. How many amps does the electrode setup produce?

I think I'm reading 200ma. It is a low reading and that is why I assume the circuit I need is more complicated than anything I've worked with in the past. I tried hooking up an inverter like the one you get for a vehicle but that didn't work. From there I hit the books and started cramming as if for a test and I'm confused when it comes to the components needed for the laws governing volts up amps go down and how to keep phase. I'm thinking that I have to bring amps up till they reach my volt down then bring up my volts but its like a dog chasing his tail. Does that make sense? Thanx again for your time and knowledge.

After seeing your second post, I'd start out by trying to power a 12v automotive light bulb. In this mode you won't need to worry about the frequency of the power.

You'll need lots of nails in the ground for this to work.

Good luck.

As a matter of fact it has so far blown the filament on two different 1157 tail light type bulbs. I got the test light to hold no problem but it had an ac capability. So I guess I just have to increase the number of cells I'm using which is no problem. I'm reading about 2.1 v every 6 to eight feet. Thanx

200ma x 12v = 2.4 watts. If you convert it to AC, the wattage will be somewhat less, say 2 watts. This would give very little heat and not much light, but it might be able to operate a radio.

What you read on the meter is voltage only. Voltage is not the same thing as power, you need current AND voltage for power. Power is not the same as energy, you need power for an amount of time to have energy. You have very little of any of the above, in fact not enough to do much of anything except maybe a transistor radio as mentioned.
