Have an idea I want to realise but...

[Milchy]

Hello there!

I have an idea I want to realize practically, but my electrical knowledge is almost zero. Everything I might have known is long forgotten. I'm asking for a good online course/site or any other resource that would provide me with enough information and examples to cal, wire, construct the following and not kill myself in the process:

0) 101 electrical fundamentals
1) A device that would let me turn AC to DC,
2) A device that would let me vary the voltage and amps on a fixed wattage. (Also, ways how to decrease or increase source wattage)
3) A device that would let me switch between a constant current and a pulsating one.
4) Information on electrical discharges, breakthrough voltages, working principles etc.

hi milchy
welcome to PF

0) 101 electrical fundamentals

do some googling and you will probably come up with some choices
also look and see what tech colleges are available in your town/city or nearby

1) A device that would let me turn AC to DC,

google diode rectifiers

2) A device that would let me vary the voltage and amps on a fixed wattage. (Also, ways how to decrease or increase source wattage)

wattage isn't fixed W = V x I ( Amps) vary either V or I and the wattage changes
increasing source wattage doesn't make electrical sense ... we use Watts to describe the power being used by a load
load = any appliance in your house, or say what parts of your car use ... ignition, lights, horn, Aircon etc

3) A device that would let me switch between a constant current and a pulsating one.

there are ways to do this, do some googling and come back with some links and specific questions on what your find

4) Information on electrical discharges, breakthrough voltages, working principles etc.

as per my answer to your Q3cheers
