1. Adding a resistor and a capacitor to the input and output of the circuit prevents current from flowing the wrong way if you make a mistake, which could cause a fire or fry equipment/start a fire etc.

2. Gain = (1 + 10k/10k)
   Gain = 2

3. Pot turned to max value:

Gain = (1 + 10k/10k)

Gain = 2

Pot turned to min value:

Gain = (1 + 10k/10k)

Gain = (1 + 0/10k)

Gain = 1

4. Gain = (-22k / 10k)

Gain = -2.2

In this video the sine wave being visualized on the oscilloscope is inverted, and being amplified. 

5. Pot turned to max value:

Gain = (-10k / 4.7k)

Gain = -2.13

Pot turned to min value:

Gain = (0 / 4.7k)

Gain = 0

6. Amplifier w/ Photocell:
