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

sometimes we overlook even the simplest of things‚ and the most valuable to our survival as a human race and as a planet. Everywhere around us people envy great architects and artists because of their remarkable creations. Though‚ we‚ as a human race disregard the importance of less tangible commodities‚ developed by the greatest artist ever‚ Mother Nature. She has given us the most magnificent and staggering artwork imaginable‚ our environment. But only through the most convoluted processes have these

An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons‚ giving it a net positive or negative electrical charge. The name was given by physicist Michael Faraday for the substances that allow a current to pass ("go") between electrodes in a solution‚ when an electric field is applied. It is from Greek ιον‚ meaning "going." The word ion also is responsible for electrical current being symbolized by the letter i in chemistry and physics. An anion

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

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

Efficiency of an Incandescent Light Bulb Alex Mendez November 4‚ 2008 Purpose: The purpose of this lab was to examine the conversion of electrical energy to light and thermal energy as well as the efficiency of incandescent light bulbs. Procedure: To design this experiment we need to have a jar with water‚ temperature‚ and an voltage source. First‚ we poured 200 mL of water into a beaker then poured into a cup. We then stir up the water and measured the initial temperature of

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

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
