Included in your kit is a manual with 10-easy-to-do experiments! Also included:
Graphite Pencil Eraser Shield 1000 Ohm Resistor Piezoelectric Gas Ignitor AF Heat Wire Line of Resistance Manual
Some examples are below. (Note: A multimeter is required but not provided in your kit.) |

Example 1: Electrical resistivity of graphite. | |||||||||||||||||||||||||||||||||||||||||||
|
|
This test is run by drawing a line with a graphite pencil. |
