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

In 1880‚ Thomas Alva Edison invented the incandescent light bulb and patented it. It’s an invention that has been around since the 1800’s. This invention has significantly‚ affected society by allowing the world to create a comfortable safe environment. Edison had come up with a 16-watt bulb that lasted for over 1‚500 hours. Edison’s light bulb needed improvements‚ and those improvements are the reason we have light bulbs today. The light bulb was invented by using a low current electricity‚ a small

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.

been in the past‚ and the choices that they make today about the light bulbs in their homes can play an important role in the future of the environment. Light bulbs are an every day object in homes across the World today and range from the less energy efficient incandescent light bulbs (normal light bulbs)‚ the more energy efficient compact fluorescent light (CFL) bulbs‚ and the most energy efficient light emitting diode (LED) bulbs. In order to help save the environment people need to make the change

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

I chose some specific articles related to Thomas Edison’s invention of the light bulb‚ and for numerous reasons. The main reason being I wanted to see what it would be like to step back in time to the absolute wonderment surrounding such an exciting and revolutionary invention. In our current age‚ when we can literally teleport objects like atoms from one place to another‚ I feel it’s safe to say the light bulb is something we all take for granted‚ at best‚ and more likely‚ don’t even think

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
