The Romer-Lewin ring with capacitors (part 1)

The Romer-Lewin ring with... capacitors.
This short video shows how the 50 Hz reactances of two capacitors in a loop lead to the same effect seen in the resistive Romer-Lewin ring: two different voltages across the very same two points. In this case the 'voltmeter' are represented by two oscilloscope channels.
Both capacitors develop a voltage that is in quadrature with the current flowing in the ring. Since this alternating current is flowing in opposite directions relatively to the common positive convention associated with the probe tips placement (when it is entering the red probe for the left capacitor, it is entering the black probe for the right one), voltage across the two capacitors appears to be in opposition of phase.
Considerations about the choice of capacitor type and agreement between computed and measured values (via RMS meter and oscilloscope) can be found in the next video.
IMPORTANT: if you plan to do this experiment on your own, please choose a non-polarized type of capacitor, because depending on the values you might end up driving high reverse (displacement) currents that won't be tolerated by the components.
