In trying to learn as much as possible about power supplies for use with a nichrome wire heating element, I think I've figured out about how much amperage I need, based on how many watts I need. Somewhere along the way I recall running into the notion that, in a straight power-supply circuit, with no resistors or divided voltages required to accomplish anything but watts, a deficiency in amps could be made up by supplying some excess voltage. In other words, volts can turn into amps to get a desired result. I've tried to find the passage that reveals that, but I can't, so I opted to open myself to ridicule and howls of derisive laughter by asking the question here. IS there any way that could work, have I been misinformed, or am I hopelessly out to lunch?
