Re: The Beginnings of a Fusor Electrical System

I've measured 8.04 volts on the specified connections. Isn't that similar to what my multimeter does to measure resistance?

Re: The Beginnings of a Fusor Electrical System

I measured 333 between the red and white wires on my multimeter's 2000K setting and a highly varying measurement between the yellows on the 20 setting.

Re: The Beginnings of a Fusor Electrical System

The transformer weighs about 15-20 pounds. How long would the run time be on a mid-duty, fusor-capable supply? Also, could you verify my opinions on wires? (Haven't tested with a voltmeter, only been few days) Here goes: The yellows are negative in/out, the red is positive in, and the white is groun...

The electrical portion is the only area of the project on which I am a little iffy, and would appreciate guidance in these matters. I hav...
