Help with theoretical probability question please?

On a practical level, a device designed for 240v input would be damaged if you fed it from a 1:2 step up transformer at 480v. But if it survived, doubling the voltage would mean it drew double the current and hence four times the power.

You need to learn some basic principles. Here is a free course: http://www.phy.davidson.edu/instrumentat...

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.
