Electrician of the week is ARIN!!
“So on Monday, we built a filament out of silver nichrome wire!” says Declan, remembering this cool day. “We awesome cause we make filament,” says Josh (geez, stop being funny!) In case you don’t know what a filament is, it’s that little wire inside of an incandescent bulb! And in case you don’t know what an incandescent bulb is, it’s:
Below, there is a diagram of the circuit we made to use the filament with. Red clay held the wires together to stand up as we wound silver nichrome wire around the two standing-up-like wires. Then, we connected the last bit. The silver nichrome wire glowed! We all felt like we were actually creating a lightbulb!
And then, today, we looked at two different kinds of circuits. Series and parallel. Two batteries and one bulb. We predicted which one would be brighter, and why? Turns out, against most of our guesses, the series circuit was the brightest!
Now, after months of talking talking nonstop talking, it’s time for… MORE TALKING! No, the quote…
“In a parallel circuit, electricity has two paths, one from each battery. Therefore, it will have the brightness of one battery, and a longer life span”
-Arin
Next week, we’re starting to make switches and flashlights. Stay tuned…
