What we know as and call "voltage" is the potential difference between two

I'll measure it for you. I am assuming sinusoidal steady state AC, isn't
everyone?

I'll bet you can. So I have this piece of clear plastic with two terminals
staked to it. Call them A and B, A about 2 inches above B as I look at it. I
have a 10k resistor wired from A to B and dressed an inch or so off to the
left. I also have a 1k resistor wired from A to B and dressed off to the
right, so the two resistors are a couple inches apart. There aren't any other
electrical connections to the two resistors. I have a pretty good AC
voltmeter, and using my best techniques, I measure one volt RMS across the 10k
resistor. Using a scope, I see it's a nice 100kHz sinewave, constant
amplitude. So what's the voltage across the 1k resistor?
