Area of Interaction: Environments

Significant Concepts: Basic circuits

Unit Question: How have circuits impacted our environments?

Define the following:
Voltage: an electromotive force or potential difference expressed in volts.

Current: a flow of electricity which results from the ordered directional movement of electrically charged particles.

Resistance: the degree to which a substance or device opposes the passage of an electric current, causing energy dissipation. Ohm's law resistance (measured in ohms) is equal to the voltage divided by the current.

Circuit:• a complete and closed path around which a circulating electriccurrent can flow.

Transistors: a semiconductor device with three connections, capable of amplificationin addition to rectification.

LEDs: light-emitting diode, a semiconductor diode that glows when a voltage is applied.

Capacitor: a device used to store an electric charge, consisting of one or more pairs of conductors separated by an insulator.

Resistor: a device having a designed resistance to the passage of an electric current.

Switch: a device for making and breaking the connection in an electric circuit: the guard hit a switch and the gate swung open.

Digital Electronics: electronics which relating to or using signals or information represented by discrete values (digits) of a physical quantity, such as voltage or magnetic polarization, to represent arithmetic numbers or approximations to numbers from a continuum or logical expressions and variables :digital TV. Often contrasted with analog .

Integrated Circuit: an electronic circuit formed on a small piece of semiconducting material, performing the same function as a larger circuit made from discrete components.

Binary Code: a coding system using the binary digits 0 and 1 to represent a letter, digit, or other character in a computer or other electronic device.

How have circuits impacted our environment? we use circuits in everything electronic.

I'm sorry, but I did not have time to finish this. I'll do it at home over the weekend, if that'll make you happy.

Now start your circuit project. Get the materials and instruction from Ms. Bradfield.


Answer the Following Questions After You Complete Your Circuit:
1. Did you like making the circuit? No. I burned myself countless times, and half of it wasn't even circuitry.
2. What did you like the least about making the circuit? Burning myself with the soldering iron, and the headaches involved with the gasses put off by the solder.
3. What did you like the best about making the circuit? Um...
4. Using complete sentences, explain how circuits can be applied in the real world. (List three)
1. I could maybe go into work for YESCO.
2. I could go into into computer construction.
3. I could be a mechanic.

5. Were you careful with the circuit, solder, and soldering iron? Yes, but I still got burned a bunch.
6. Were you respectful and nice to other students? Yes.
7. Did you take a picture of both your circuits and add them to this wiki page? No because I took my circuit home already.

1. Did you have a good attitude answering the questions? Explain: I had a very positive attitude until i burned myself and gave up.
2. Did you have a good attitude making the circuits? Explain: My attitude was awesome. What are you asking for?
3. Were you a whiny baby during the circuit unit? Explain: I took all of my burns like a man, not a whiny baby.
