CAN SOMEONE HELP ME EMPHASIZE THESE??



Experimental Procedure • All the fruit to be used were rolled with the palm on a tabletop in order to loosen the juice inside the fruit. • A slit is made at one end of the fruit and the galvanized nail was deeply inserted into the fruit carefully, the galvanized nail was made to get to the center of the fruit but a little bit of it remain outside the fruit so that the connecting wire or alligator clip can be attached to it. • A slit was made opposite the galvanized nail of the same fruit and the copper penny was inserted into the fruit leaving a little part outside the fruit. The electrodes are placed opposite each other because the farer the electrode the higher the voltage it will produce. The two charged electrodes will now permit the flow of electrons through them. • The voltage produced between the electrodes was measured by hooking two alligator clip to the two electrodes and connecting one of the multimeter terminals to the copper and the other terminal to the galvanized nail to measure the volt present, when connected in series the two end of the alligator clip was connected to the terminals of the multimeter. • All fruit was connected together with an alligator clip. An end of alligator clip was connected to the penny of a fruit, and the other end to the galvanized nail of another fruit, an alligator clip was also being connected from the penny of the second fruit to the galvanized nail of the third fruit then the connection goes on like that to the last fruit. The two remaining end of the experiment will be connected to the LED. After this series of connection, the LED light up. The different cells make up this battery.​
