In the current issue of energy energy is not sufficient or needs more energy, especially energy, in the form of light to illuminate without access to electricity in many areas. By this research study of galvanic cells with the purpose of designing and crafting lamps, portable energy from galvanic cell experiments by finding the appropriate electrode, and find the variables that affect the occurrence of electrical energy. Complicity by the trial of Martin's base surface of metal electrodes to work affect electrical power occurred or not, and the number of electric cells affect the occurrence of electrical energy or not. By finding the appropriate electrical experiments that compare the results of experimental calculations from the theory and results from experiments. By using metal zinc, magnesium, copper, lead and Tin. This experiment by using full-electric cell cell cell 300 ml water and salt 1 3 grams and measuring electric currents and voltage values and experimental textures affects the occurrence of electricity then. Try using copper and magnesium electrodes electrodes which have trials that copper and magnesium is a metal, clamp and voltage values the most, including the surface of copper, electricity and more, electricity peak at 49.3 mAh.When using the touch surface Cebu 1080 cm2 but not affect the voltage values do not increase or decrease. To add a magnesium surface does not cause the value of electricity, but the resulting electricity, reduce slightly, including the value of the voltage does not rise, and when the increase in the number of electric cells. Electric current does not have to be changed, but there are more and more voltage value enough for the use of a 3 volt bulb and found from experiments can lead to experimental design and fabrication.
