INVESTIGATE:  Define the following: Voltage: force measured in volts

 Current: the time rate of flow of electricity charge

Resistance: slows down current of electric charge so nothing blows up

Circuit: path of electricity

 Transistors: amplifies current

LEDs: Light Emitting Diode: a diode that emits light when conducting current

 Capacitor: a device used for accumulating and holding a charge of electricity

<span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 130%;"> Resistor: a device designed to introduce resistance in a curcuit

<span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 130%;"> Switch: a device used to turn on and off an electrict current

<span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 130%;"> Digital Electronics:

<span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 130%;"> Integrated Circuit: a circuit of transistors, resistors, and apacitors constructed on a single semiconducting chip

<span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 130%;"> Binary Code: a system of representing numbers and letters

<span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 130%;"> How have circuits impacted our environment? Withput circuits we wouldnt have lights, without lights we wouldn't be able to see in the dark and wouldnt have many of the luxuries we have including computers, televisions, ipods, and movies. We also wouldnt be able to travle at night or function at night.
