Kierra Roberts 1-4-11 11B How Do Batteries Work? Electricity is the flow of electrons through a wire‚ that is called a circuit. Batteries have three parts to them‚ an anode‚ a cathode‚ and an electrolyte. The cathode and the anode are hooked up to an electrical circuit. The chemical reaction that is happening causes the electrons to build up at the anode. When the circuit is closed the electrons will be able to get to the cathode. When the electrochemical process change the

Battery Charger Kingsley Nwador ECT 598.001 Senior Project 10/15/08 A battery charger is a very unique and widely utilize device in the world today. Its applications spread from home consumers all the way to business owners and industrial workers. But what is a battery charger‚ one might ask. A none technical definition would be‚ a battery charger is a device used to recharger my batteries such as in my digital camera. Perhaps a better definition would be‚ a battery chager is a device

there were batteries slim‚ flexible and also powerful enough to run the gadgets. The batteries‚ it turns out‚ are the main barrier to modern electronics design. But in a small‚ brightly lit lab in an office park behind the Oakland Airport in Alameda‚ Calif.‚ a young startup called Imprint Energy‚ is using research created at the University of California‚ Berkeley to develop just such a battery that could free gadget makers from the constraints of the standard lithium ion battery. Well‚ that’s

BATTERIES What is a battery? A battery is a container consisting of one or more cells carrying an electric charge and used as a source of power. SECONDARY BATTERIES * rechargeable * high cost (short-term) low cost (long-term) * used in objects with high energy requirements: e.g. mobile phones‚ power tools * require special handling‚ containment & disposal * limited interchangeability * long life time * produce smaller amount of waste (flat discharge curve)

study aims to find out how long a lemon (Citrus limon) can last as a lemon battery powering a digital clock. B. HYPOTHESIS The researcher assumes that one lemon would last for a day or two and that the usage of more lemons would entail a longer battery time. C. OBJECTIVES Specifically‚ it aims to: 1) come up with a quantity-longevity ratio with the use of a varied quantity of lemons in the production of a lemon battery 2) find the relationship of the number of lemons and the time it powers
