Of these, the best known is the Leclanche, consisting of a glass jar filled with a solution of sal-ammoniac in which is placed a rod of zinc. The chemical action that takes place whilst the current is flowing results in the wasting of zinc. Actually, when the cell is at rest, chemical action continues to a certain extent owing to the impurities contained in commercial zinc, and the rod wastes away, but this can be obviated by coating or amalgamating the rod with mercury</FONT></div> <div> <B>A</B><FONT SIZE="3" COLOR="#000000" FACE="Arial" >lso immersed in the solution is a porous pot containing a plate of carbon, around which is packed a mixture of crushed carbon and manganese dioxide. The carbon provides the positive current, the zinc rod the negative. Leclanche cells are used extensively where current is required occasionally and for short periods, as for such purposes as ringing house bells.</FONT></div> <div> <FONT SIZE="6" COLOR="#000000" FACE="Arial" ><B>A </B></FONT>modified form of the Leclanche cell is the so-called "dry battery". Actually these batteries are not dry, for if they were there could be no flow of current. In a dry battery the zinc rod is replaced by the containing vessel, and the liquid by <I>a </I>moist paste that surrounds a carbon rod in the centre of the cell. The whole cell is sealed at the top and placed inside a closely fitting tube. Such dry batteries are in modern day use for all manner of purposes from flash lamps to radio receivers, their great advantage being the ease with which they can be carried about in any position.</div> <div> <B><U>Computer Corner</U></B></div> <div> <FONT SIZE="6" COLOR="#000000" FACE="Arial" >T</FONT><B>he club main web site</B> and technical web site are kept updated with the newsletters plus circuits and technical information.
