A battery‚ which is actually an electric cell‚ is a device that produces electricity from a chemical reaction. In a one cell battery‚ you would find a negative electrode; an electrolyte‚ which conducts ions; a separator‚ also an ion conductor; and a positive electrode. Batteries are made of magnesium dioxide‚ graphite‚ electrolytes‚ zinc oxide and a paper soaked in an electrolyte solution. All of this is sealed in a insulated tube for safety. http://answers.ask.com/consumer_electronics/other/what_are_batteries_made_of

the tendon‚ and then cut off the tibia bone. Moreover‚ we measured the resting length of the muscle. After that‚ we tie a suture around the tendon and placed it on the femur clamp‚ and then we placed the stimulating electrodes touched the belly of the muscle‚ and the stimulating electrodes was attached into the stimulator output panel. We also needed to keep the muscle moist all the time by using frog ringers solution. Next‚ we started the first experiment by using the computer and open the program

confounding variables which could have impacted the experiment’s results. The EMG(or electromyography) and the AD Instruments Powerlab system to see the data‚ was used to measure the amount of electrical activity produced by skeletal muscles‚ and the electrodes were placed on parts of the ab muscles on the stomach after being rubbed by alcohol swabs. The experiment was over the course of three days‚ the first day was used to obtain a baseline for all of the participants‚ which required the

the positive electrode. How does gel electrophoresis work? First a gel is prepared. Gels are made of agarose‚ a seaweed extract similar to gelatin. The finished gel has a consistency similar to very firm jello. This consistency offers resistance to the pieces of DNA as they try to move through the gel. The gel is prepared with wells at one end so that DNA samples can be loaded into the gel. 1 2 3 4 5 - electrode 6 direction of migration Wells for loading samples - electrode + Side View

Liquid Crystal Displays (LCD) – Working We always use devices made up of Liquid Crystal Displays (LCDs) like computers‚ digital watches and also DVD and CD players. They have become very common and have taken a giant leap in the screen industry by clearly replacing the use of Cathode Ray Tubes (CRT). CRT draws more power than LCD and are also bigger and heavier. All of us have seen an LCD‚ but no one knows the exact working of it. Let us take a look at the working of an LCD. We get the definition

Investigatory Proposal: Organic Batteries VS Commercial Batteries (7-Rizal Grp.5 2009-2010) I. Introduction A. Background of the Study In the 21st century‚ billions of people rely on electrical energy in one form or another. Today‚ even in some of the most remote regions‚ electricity powers lights‚ radios‚ televisions‚ and many other devices that help people to be more productive‚ comfortable‚ and informed. In some places‚ electricity is generated by hydro-electric dams or coal-fired power
