ok...so here's me question.

with increasing voltage i should increase current?

why does it work to the opposite...

even a small begginers lecture would be much appreciated

Volts = Current * resistance, so voltage is proportional to current with a coefficient of resistance.

Ex: We have 5 volts going through a resistance of 0.5 ohms, what will the current be?

5 = I * 0.5

5/0.5 = 10, so 10 amps.

Double the voltage and see what you get.

What circumstance are you referring too?why does it work to the opposite...

lets say you change that load to 1500 watts with a ohm load of 2.67 still the same voltage but obviously with an increse in current...but the same voltage....

but the confusing thing to me is if you do increase the voltage then you in fact increase current...that fact has been pointed out to me..(thanks by the way!!)but all the research ive done always says voltage drop increases current...why

A decrease in voltage decreases current if all other factors remain constant.but all the research ive done always says voltage drop increases current...why

In an AC circuit a change in current can lead or lag a change in voltage. Could that be what is confusing you.

what other factors would those be?

In this case resistance.

....so would increasing resistance decreases current....if voltage is held constant?
