What do high school physics teachers and physics experts think of U 1 and U2 in the first picture?

The circuit structure is very simple. Power supply, R0 and R are connected in series, and then the voltage corresponding to U 1 is divided by R. Because the capacitor corresponding to pQ is connected in parallel with R, the total current is calculated and multiplied by R, which is U 1, while the capacitor corresponding to MN and its parallel part are part of R, and the radiation is R 1, so the total current multiplied by u 1 is U2.

Got it!
