23.- Conductor tester
With this conductor tester you may
identify which daily life items are
conductors or not. To do this, you
only need to bridge the article to be
tested between A and B. If the lamp
lights up, the item is a conductor
(may be a knife or aluminum pot).
If the lamp does no light up, the
item is not a conductor, could be
plastic or wood.
