Where to Learn
More
Click on the highlighted portion
of the component in the circuit
to begin building your very own.
Please click on the section of the
circuit that is highlighted
Try Again
This will be the second point of contact for the
first conductor in the circuit. Usually after the
power source a switch is placed to safely
control the flow of electricity in the circuit and
to the load.
Please click on the section of the
circuit that is highlighted
Try Again
The first conductor, or wire, has be connected
between the power supply and switch.
Continue by clicking on the first connection
point of the second conductor.
Please click on the section of the
circuit that is highlighted
Try Again
There are two electrically conductive parts of
the light bulb, either one connected to one
side of the filament, select the first.
Please click on the section of the
circuit that is highlighted
Try Again
The beginning of the final
conductor, on the second
terminal of the lightbulb.
Please click on the section of the
circuit that is highlighted
Try Again
This circuit is almost assembled.
Attach the final conductor to the
negative terminal of the battery.
Please click on the section of the
circuit that is highlighted
Try Again
Now that it is assembled, all
that is left is to flip the switch
from the open position to the
closed position to make the
entire circuit live with electrical
energy.
Please click on the section of the
circuit that is highlighted

Great! It seams to be
working fine. All circuits are
more or less like this one,
circuits may be customized
to fit many purposes in an
unlimited amount of ways.

Power Engineering
• Power engineers deal with the generation, transmission, and
distribution of electricity and design of power electronics.
Engineers follow strict guide lines of the National Electrical
Safety code and National Electric Codes to ensure safety and
reliable power.
Communications
Engineering
• Communications engineers design the devices and medium for people all
around the world to connect with each other, from the invention of the
telephone in 1876 by Alexander Graham Bell to FM radio in 1890 by Edwin
Armstrong. These engineers use complex theories to deliver all kinds of
messages at high speeds around the world utilizing technologies such as
fiber optics and 4G wireless data.
Computer Engineering
• Computer engineers deal with more of the computer system
itself, the operating system and the software it takes to give
the user interfaces we are all familiar with like Microsoft
Windows or Apple’s Mac OS. Engineers design software for
websites and for more recreational purposes like videogames.

Microsoft, Paul Allen and Bill
Gates in 1975 when the
company was founded.

Micro-Electronics
Engineering
• Micro and nano-electronic fabrication engineers design and build devices
that are microns wide, working at such a small scale poses new challenges
that aren’t considered for larger builds. The circuits they build are usually
on Silicon wafers layered with different components and geometries
constructed through methods of growth, deposition, etching and more.
Often the product is the processor chip, which small but powerful can run
entire computer systems.
A micro-fabrication engineer working in a clean
room. They have to extra caution not to bring
dirt and other contaminants into the room to
protect the nano-devices from possibly being
ruined if a speck of dirt were to come in contact.
A silicon wafer is usually the base
on which circuits are built on due
to its ideal semiconductor
properties
