Just like any normal battery my salt water battery has the three main components‚ the electrolyte (in case you didn’t know its like a liquid that conducts th electric current (I hope I spelt that right))‚ a cathode (the negative electrode) and the an anode (the positive electrode). As you may or may not know a chemical reaction must occur so that that chemical energy can be converted into electrical energy which is then used for whatever. In my salt water battery the electric current passes through the

Eugen Goldstein studied the light emitted from a air filled glass tube when current was passed through it. He noticed that not only were their electrons and cathode rays traveling toward the positively charged end (anode)‚ there was a third ray that traveled away from the anode end to the cathode. While observing this ray he noticed how it passed through the holes‚ or channels of the cathode. He named this ray the “canal ray”. Since the canal rays traveled in different directions from the cathode

9.1.1 Define oxidation and reduction in terms of electron loss and gain. Oxidation: the loss of electrons Reduction: the gain of electrons 9.1.2 Deduce the oxidation number of an element in a compound. Always determine elements that never change their oxidation number then ensure the charge of whole molecule is right. N.B. Atoms in elemental state have oxidation numbers of 0 9.1.3 State the names of compounds using oxidation numbers. Example of this in iron‚ can be iron(II) or iron(III) 9.1.4 Deduce

Lead Acid Cell vs. Button Cell Lead acid cells were invented in 1859 by the French Physicist Gaston Plante‚ and are the oldest types of rechargeable batteries. These types of batteries typically weigh at 5kg‚ but can range from half a kilogram to over 30 kilograms on the consumer market. Though their chemistry means a very low energy-to-weight and energy-to-volume ratio in comparison to other modern batteries‚ their ability to supply high surge currents means that the cells maintain a large

RENEWABLE ENERGY RESOURCES ABSTRACT The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. It is also now widely recognized that the fossil fuels (i.e.‚ coal‚ petroleum and natural gas) and other conventional resources‚ presently being used for generation of electrical energy‚ may not be either sufficient or suitable to keep pace with ever increasing demand of the electrical energy

cell vehicles‚ including automobiles‚ buses‚ forklifts‚ airplanes‚ boats‚ motorcycles and submarines. There are many types of fuel cells‚ but they all consist of an anode (negative side)‚ a cathode (positive side) and an electrolyte that allows charges to move between the two sides of the fuel cell. Electrons are drawn from the anode to the cathode through an external circuit‚ producing direct current electricity. As the main difference among fuel cell types is the electrolyte‚ fuel cells are classified
