# Phase shift

Hello,

I was wandering if the following is possible.
I have a huge voltage 3kvolt, when is passed through a coil my voltmeter is
showing me negative voltage. I would like to phase shift this or invert this
so to get positive voltage How do I go about this?
....I heard that inthe 70's, some cars where negatively based, and used such
converters to get positive. now I believed everything is positive.

thank you

Actually I meant current not voltage. the ampmeter shows negative after the
inductor (coil).
And this is pulse DC not AC, so shifting by PI wont do it, I guess I need
to invert this.

3kV is high, but hardly huge.
Start with a study on the characteristics of AC and DC. Check back
when you know a little about that topic. Have fun!

Is there a good reason why you can't just connect the meter the other
way round?

Oh, that's different.

very carefully.
yes, but they were used 250 times less voltage

it might be easier to modify your 3000V souce to produce a positive voltage.
