DC Circuits: Electric Power PHY 114 Lab Report 10/09/2013 Abstract: The purpose of this experiment was to look at electric power dissipated in a load resistor in a circuit with a real power source‚ which has a finite internal resistance. We discover a surprising result about how to deliver the most power to a device from a source. Consider a simple circuit in which a battery of voltage drives a current through a resistor of resistance. As we have seen‚ the battery is continuously doing

Making a Potato Powered Light Bulb Materials: A large potato Two pennies Two zinc-plated nails or screws Three pieces of copper wire A very small light bulb or LED light 1) Get a potato and cut it in half. Then make a small slit in each half just big enough to put a penny into. 2) Cut two pieces of copper wire and wrap one around one of the pennies a few times‚ and wrap the other one around the other penny a few times as well. 3) Take a third piece of copper

with a green light bulb? Why or why not? It would not be a wise choice to put a plant under a green light bulb. The reason for this is that due to the fact that the leaves are green they reflect green light. This shining green light onto the flowers will cause photosynthesis to stop. Since the light is being reflectd‚ the cells do not get any light. With out light they cannot carry out the everyday occurrence of photosyntesis. If the choice was mine‚ I would place them into violet light‚ because

I love seeing children have "light bulb" moments. It’s moments like those that let you know you have chosen the correct profession. I also chose teaching as my profession because when I was in elementary school I did not have good teachers to look up at. I struggled a lot in elementary school and my teachers just saw me as the problem child they did not have time to help. They made me feel horrible because I didn’t know the answer to a question they asked‚ or I needed help with something they thought

I do not agree that companies should stop investing in “pushing promotions” and put their money into attracting consumers to the company with so called “pulling promotions”. They each serve their purpose in the very diverse market of consumers. “Pushing promotions” are more useful at the start of a

artwork titled “Light bulb to Simulate Moonlight” (Figure.1)‚ 2008‚ is currently showing at the Ingleby Gallery in Edinburgh. It aims to imitate the moonlight through artificial means. The artwork seeks to connect the viewer with nature‚ which provides transportation to the place and confronts the cyclical relationship between humankind and nature. In Collaboration with an engineer from Osram ‚ they measured the moon’s light spectrum and interpreted it to incandescent light bulbs as same as standardized

EVOLUTION OF LIGHT TECHNOLOGY Case Study TETA 1507: Technology Management Group Members: Muhammad Iqbal Adnan Saleem Muhammad Usama Mazhar Kashif Ihsan Khattak Muhammad Imran Anwar ABSTRACT Light has started from the sunlight and moonlight‚ and then the fire has changed the concept of light. Humans made torches from wooden sticks‚ lamps from rocks‚ bones and pottery‚ candles from bee wax‚ oil lamps and gas lamps but fire was common thing in all these eras which actually produced light.

alternative light bulb which is designed to lessen the consumption of electricity Florescent light bulbs are oftenly used for light in houses But sometimes the light bulb became wrought and because we think electricity is too expensive‚ We create an alternative light bulb using everyday materials. In this experiment‚ we will try to replace light bulbs with alternatives and cheaper replacements. In this investigatory project the group will try to make a plastic bottle light bulb.

not live without them. Thomas Edison’s light bulb has been one of the biggest impacts on society even to this day. Thomas wanted to replace the gaslight with a mild‚ safe‚ and inexpensive electric light. Edison invented the light bulb in 1879‚ and to this day the light bulb is still just as useful‚ if not more so. As time has passed‚ the light bulb has grown more important with more and more functions. Just think about how many different types of light bulbs we have now... in civilized areas there
