Respect!! :D I like open minds, and people willing to challenge things that they grew up with and ask "does it need to be this way?"
I used to be interested in the nature of electricity when I was younger. I've lost much of the fascination, but can still recall bits of terminology.
IIRC correctly, when current passes through a transformer the wattage remains constant but the ratio of voltage and amperage is adjusted. Something about higher voltages being easier to transmit across a long distance (am I correct so far). If so, when you adjust the power setting on an appliance, for example the control unit on a model train set, are you adjusting the voltage, amperage or both being the wattage? If it's the voltage being adjusted, then would this affect your definitions?
I started typing a question about static electricity, but the electrons in my brain are too worn out this evening.
