Functioning, Energy Transfer, Pros and Cons of final product:
So, above is the final demonstrations of my project (flashlight). The most obvious energy transfer here is electrical potential energy, which was stored in the battery, to light energy, shown when the lightbulb lights up. On a lighter note, the project has definitely reached its primary purpose: the electrical potential energy is, by all means, transferred to light energy, as (1)the lightbulb lights up after I connected a black wire from the negative side of the battery to the positive wire of the lightbulb, while the negative wire of the lightbulb directly touches the positive side of the battery.
Thus, in this case, the battery is the source of the electricity. And, when all the parts(for reference, please refer to (1)) are in the correct contact, the electricity will begin flowing through the wires. So, this is essentially a basic electric circuit, where a battery is connected to a lightbulb, and where through the black wire the current flows from negative terminal of the battery to the lightbulb and flows across the filament of the LED lightbulb. And, this will convert some of that electrical energy, which started from stored electrical energy in the battery, to light energy. Furthermore, due to the reason the batteries are arranged (that is – + – +), the current will then flow through the battery to return to the negative terminal of the battery, which is also will the entire process will start again. And, this is also why contact must be very good throughout the flashlight to prevent hindering the electric circuit, which will cause the flashlight to stop lighting.
My goal for the project is to make the customers be able to watch their feet and at the same time in front of them in the dark, when having to travel distances. To achieve this mean, I have made the flashlight into a t-shape, with one of flashlights having a lightbulb that can shine in front and the other flashlight being able to shine down, and that is the purpose of the t-shape.
Overall, my project was pretty successful. However, personally, now I have realized the LED lightbulbs are too small and thus its effects are not as big as desirable. So, next time, if I can do the project again, I will most likely, instead of seeking for convenience and going with the LED lightbulbs supplied in the classroom, I will purchase bigger-volts lightbulb. As a result, the battery volts will also have to increase and thus I want to increase the general scale of the project.
Another thing that I believe to be a con of my project, is that though throughout my developing my prototypes, I have constantly strived and worked tirelessly towards the aesthetics of my flashlight; however, at its current state, I will have to admit that the flashlight is still not very pleasing to the eye. And, that would be another less significant area of improvement.
Impact of this project on environment and potential client/consumer:
The impact of this project on potential clients is that with this flashlight, the customers can see their feet and what is in front of them at the same time in the dark, while normal flashlights will only allow them to shine on one at a time. The tiny negative impact that this project will have on the environment is that it will consume more energy, because this flashlight is a combination of two flashlights, so as a result, it would need more batteries and thus more energy.
