- Determine the values of V1 through V4 for the circuits shown in the following figure (Fig. 7.43b). I believe this Superposition Theorem. The circuit below has 4 resistors but my examples have only 3. The question seems ask for the voltage values but others have included current values. I do not know how to calculate V4. I am not sure if I use the equivalent of V3||V4 for V3 and V4 voltage. I will leave example photos out my book but it does not show how to do V4.

The first step is to split the circuit into two single source circuits. These circuits (along
with their series equivalents) are shown in Figures 7.6b and 7.6c. For Figure 7.6b,

- 2. An Automatic Night Light uses a photocell to detect the amount of available light in a room. Under strong light the resistance of the photocell is 1kn but goes up to 100k2 in total darkness. The photocell is put in series with a 4.7k2 resistor so as to make a voltage divider when the ends are connected between +5V and GND as shown. As it gets darker in the room, the resistance of the photocell goes up and raises the voltage on the "Sensor Voltage" line. At "dusk", the photocell has a resistance of 10k2.
