Depends on the supply voltage. For UK 230 Volts, 1800 Watts would mean the current drawn was 7.83 Amps Watts=Volts x Amps, so Watts divided by Volts gives the current in amps.
The power bill is important but what about the safety of having something around that could not only give you a bad shock but kill you if not treated correctly by the user.Be forewarned all you testing sites out there that perform their test in the open on a lab table that this kind of amperage can do a lot of harm. I just read some where that a test site was is.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
