Voltage vs. current in an incandescant..
As pointed out by others, the incandescent is close enough to being an
ideal resistor in the steady state, but has a big inrush current.
When we worry about Voltage vs current is in a florescent. That curve
looks like a mountain range. In order to make steps in brightness, I
drive with an AC current source and a slow feed back loop with an opto
diode.
