Circuits (Blog Post #3)

LIGHT BULB! How do these machines work?  To complete a circuit and to light a lightbulb you need a closed circuit. The electrons in a circuit need to complete in a full round. The electrons will travel through the light bulb and light the bulb up.  Circuits are very complicated machines. Some of these circuit make a bigger and brother lightbulb with more volts of power but some are conservative and more dim. Tech has been very interesting . I have learned so much tech stuff in this class. I now know about atoms, elements, etc. I am exited to see what we learn next. Different materials can conduct better electricity. Wood does not conduct but metal does. Circuits are innovating things.
