Measure the individual voltages as shown.
![]() Measurement of the voltage U1. (Enlarge) |
![]() Measurement of the voltage U2. (Enlarge) |
![]() Measurement of the voltage U3. (Enlarge) |
![]() Measurement of the voltage U4. (Enlarge) |
![]() Circuit diagram voltages in the circuit. |
The three measurements are (ideal values)...
U1 = 9.00 V
U2 = 8.25 V
U3 = 0.75 V
U4 = 0.75 V
Now to can verify the KVL. But first you need to recognize all loops...
