sing the Principle of Superposition, find V2.

find theoretically and simulated the voltage and current in all resistors, if for all circuits the resistance values ​​are: - R1=100Ω, R2= 100Ω, R3=10Ω, R4= 20Ω, R5=40Ω, R6= 40Ω - The voltage E = 5VDC and E1 = E2 = 10 VDC- Solve theoretically

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. Automatic Night Light 5v Vdd a. What will the range of the sensor voltage be as the photocell +5V goes from 1k2 (bright light) to 100k2 (total darkness)? Photocell b. Write the equation for VoUT expressed in terms of the op-amp Sensor Voltage LM358AD Vout U1A mmarceau 5V inputs and gain. What is the maximum range for Vour? Reference R4 24.7ka Voltage (V) White LED C. Assuming the light is to come on at "dusk", what must the POTENTIOMETER reference voltage be set to to have the LED…
