B. In this circuit, we utilized a(n)...

- Electronic PNP Transistor: a semiconductor device use to amplify and switch electronic signals and power

- 4.7K Ohm Resistor: resistors reduce current flow and act to lower voltage levels within circuits 

- 3.3 uF Electrolytic Capacitor: a polarized capacitor which user an electrolyte to achieve a large capacitance 

- 0.1 uF Ceramic Capacitor: a fixed value capacitor that is constructed of layers of ceramic and metal material acting as an electrode (flow of electrons) 

C. How It Works:

In this circuit, we have a resistor to control the current flow. In this board, we are mainly utilizing the first, second, and third battery, as seen by the origin of the wires. We have wires connecting to the Power Trans for the circuit. We have wires connecting to the switch, which turns the sound on and off, and connecting to the frequency and volume, which we used to adjust the fish caller sound. The PNP Transistor directs the flow of current within our circuit. 

D. In this circuit, we were far more prepared, but still encountered difficulty. After connecting the resistors, transistors, and capacitors, we moved on to connecting the wires to the appropriate places. Once we finished and hit the switch, there was no sound. Our first mistake was missing the wire connected to spring terminal 68, which we fixed and still had no sound. Mr. E went through each piece with us, checking that we had each resistors and capacitor correct. 

     In the end, it turns out that the Electronic PNP Transistor was backwards. In this process, we retrained to the front of the book for directions to find which wire was E, C, and B. Once in place, our sound was working and we used to frequency switch to change the sound and tone of the caller. I'm pretty sure we heard some fish rustling in the lake!
