Figure 20. The measured voltage in this figure is 6.23 V DC.
The measured voltage around the 680 Ω resistor is 2.94 V.
Figure 21. The measured voltage in this figure is 2.94 VDC.
The measured voltage around the 47 Ω resistor is 0.33 V.
Figure 22. The measured voltage in this figure is 0.33 V DC.
So we can count on our calculation, we will always find these small differences
between the calculations and the real measurements because of the tolerance of the
components.
