emmediatley the first thing i thought of before even started the lab was the shake weight, the weight that shakes while you hold it to work out your arms and stuff, good workout!! But i liked this lab probably the most so far because it was very hands on and that is the best way i work, even the other labs were more of the objects doing the work and this time it was myself doing the work. It made it easier to know what exactly i was doing and what the entire lab was about.
This Lab was all about conducting electricity, i found that the faster you shook the generator the more electricity it gave off. This all has to do with Faraday’s Law:
“In Faraday’s first experimental demonstration of electromagnetic induction (August 29, 1831[9]), he wrapped two wires around opposite sides of an iron torus (an arrangement similar to a modern transformer). Based on his assessment of recently-discovered properties of electromagnets, he expected that when current started to flow in one wire, a sort of wave would travel through the ring and cause some electrical effect on the opposite side. He plugged one wire into a galvanometer, and watched it as he connected the other wire to a battery. Indeed, he saw a transient current (which he called a “wave of electricity”) when he connected the wire to the battery, and another when he disconnected it.[10] This induction was due to the change in magnetic flux that occurred when the battery was connected and disconnected.[8] Within two months, Faraday had found several other manifestations of electromagnetic induction. For example, he saw transient currents when he quickly slid a bar magnet in and out of a coil of wires, and he generated a steady (DC) current by rotating a copper disk near a bar magnet with a sliding electrical lead.”
While shaking the generator you could hear something going back and forth back and forth, this was the battery connecting and disconnecting which is creating a current flow.
this shows the ways voltages can be generated http://hyperphysics.phy-astr.gsu.edu/hbase/electric/farlaw.html
I have a windmill in my town that is a good source of electricity however it isnt that dependable because it depends on the amount of wind, if any.
Its amazing how many things can produce energy although we choose to stick with nuclear power plants. I do realize they are a great source of energy however the way they only last about 30 years, no one has figured out a sufficient way to destroy one either whihc is a huge downside to the building and possible re-building of the nuclear plants.
I agree with your idea that is it difficult to rely on energy from both power plants and wind turbines because energy like this isn’t always as efficient as we need it to be. The turbines rely on the wind which obviously isn’t always there and the power plants have a short life expectancy and cost a fortune to replace.
I really enjoyed how this blog related to the other concepts, and didn’t necessarily focus on just the experiment itself. The explanation of Faraday’s Law coupled by the picture was a good way to really enhance the entirety of the blog. The connection to the generation of windmills and nuclear power plants was a good way to see the “real life” use of the purpose of this blog overall.
