Question

MAKE YOUR OWN CELL
ANS : You will need a few things to make a cell. First get two injection bottles. Then cut two 3cm long bits of thick copper wire. Use sandpaper to scrape about 1cm off the coating off both end of wires. Break and open a discharged dry cell and remove its outer metal covering (made of zinc). Cut 2mm wide and 3cm long zinc strip from zinc plate and a copper strip from a copper plate. Insert the copper strip and zinc strip seperately into the rubber caps of the injection bottles. Ensure that the copper strip and zinc strip do not touch to each other.

Now take a wire and connect the zinc strip of one bottle of the copper strip of the other bottle. Fill bpth bottles with sulphuric acid. Carefully close the bottles with the caps in which the copper wires and zinc strips are inserted.

Your cell is ready. How will you test it? Take an LED (Light Emitting Diode) Attach two wires to its two terminals. Touch the wire from one terminal to the copper wire of the first bottle and the wire from the other terminal to the zinc plate of the second bottle.
