23.- Conductor tester
With this conductor tester you may
identify which daily life items are
conductors or not. To do this, you

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.
