1. Define and explain these circuit components and how they are used in circuits:

battery- stores enegy to be used in a circuit.

resistor

potentiometer- this is a variable that changes the amount of amperage flowing through the circuit.

LED- Light emitting diode, it is a diode, which only alows the current of a cuircuit to flow one way, that produces light.

Diode- only allows electricity to flow one way through a circuit.

conductor- a material that electricity can flow through.

Capacitor- stores electricity and puts it out in a large burst, rather than a slow feed like a battery.

2. What can you do now that you couldn't do at the start of this course?

I can now understand cuircuits and troobleshoot them as well as produce them. At the start I only knew simple things, however now I know what every part of a circuit is and I can follow it through to see how it is put together and atleast supossed to work. By this I can then see what could be possible problems in the circuit. Finally, I was able to produce an entire circuit.

3. Explain the process of taking a circuit from concept, schematic, breadboard, perfboard to custom circuit board. Use examples that illustrate what you personally have done. What is the role of troubleshooting?

First, is that the circuit has to be designed on a computer, we used Eagle PCB. In this program one must find and connect all the parts of the circuit and then organize the pieces on a circuit board. Next, one has to print out the board on a peice of draft paper and transfer it to a one sided circuit board that has already been cut to size. (If the board is double sided then one has to sand the copper off of one side of the board.) Using an iron one has to put the draft paper face down on the circuit board and tape it in place, then heat the paper with the iron once ready(ink is pretty well stuck on the circuit board) then soak the paper and board in water and peal the paper off carefully enough to leave the ink on the board. after this, one must touch up the lines with a black sharpe. Following, one must uses pharic chloride to burn the excess coper off of the board. heat speeds this process. So a hot plate of some kind uner the container of chloride is helpful. make sure to check the board often becuase if one is not careful the coper that is covered with the sharpe will eventually burn off as well. once finished with this step, one must clean the board with water and drill holes to place the components in. Then organize all the parts of the cicuit on the board in their respective holes. Fially solder the components in place making sure to get a good connection with every wire.

4. What was the most useful thing you learned from this course?

I learned all about the different parts of a circuit and the concepts of a circuit. Such as ohm's law and current. I will be able to use this for years to come. Espescially, in electric cars.

5. What was the most surprising thing you learned from this course?

The most surprizing thing that I learned was how strong and awesome our big leyden jar was. I couldn't believe that is actually worked let alone, produced a huge shock. That was definetely fun, exciting, and surprizing all in one.
