Measuring the effect of a resistor
I was wondering how to choose the component values and wire lengths such that I can observe a different voltage at node1 and at node2.


You'd have to make R2 and the wire connected to it as long as a significant fraction of the wavelength associated with your signal frequency.

For the given 1 kHz signal, the wavelength is about 300 km. To be able to observe a significant voltage difference between your NODE1 and NODE2, you'd want to make your resistor and wire at least 10 km long.
