can you put that into layman's terms?
balanced relative to ground?? ??

in any circuit you have a B+ and a ground(not to be confonded with earth ground).
the first is the positive side of the circuit, the other is the negative.
everythings in between those 2 are relative to either of them, but the negative side is commonly used and termed as the circuit ground.

Tesla wasn't looking for amps. He wanted to get frequency of spikes instead of dc amps.

i was just pointing out that you can play with the current at the multiplier output to some degree.
you want less current, lower the cap's values.

What is a ballun?

thanks,

jeanna

A ballum is the tiny toroid just under the TV aerial, it changes the signal from 75 ohms to 300 ohms ladder wire, then another is placed inside the TV itself to convert the signal back.
They are also known as matching transformers.

They have the usual primary winding, but I have seen them used as a signal splitter, which is having a single output or several all off the same toroid core.

If a house is in a deep valley and cannot get a TV signal.
Place a TV aerial on top of a hill whith a ballon, connect a 300 ohm ribbon cable to it, get another same size aerial (with another ballon) connect them both up, and point it down towards the valley.
Then all the TVs will receive the signals, and no electric power is involved, it is a passive TV transmitter.

The question is when does ac star working looking like dc , at a real high freq would it look like a constant .

never.
if you don't rectify it it will keep it AC/pulsed properties.

[jeanna]

never.
if you don't rectify it it will keep it AC/pulsed properties.

YES!

@MK1
and pulsed DC looks like a sinewave when it is plotted over time on the x axis!

@Jim,
Thanks . I understand what a ballun is now.

BUT,,,,will the same   100 watt light bulb take more current to run, 
if it is a bulb rated at 240v at 50Hz or

The watts on the label is the power the bulb uses, not how much light it makes. The light it makes is the Lumens it produces.
