Pencil Graphite Resistance Experiment at Lara Caley blog

Pencil Graphite Resistance Experiment. It does this by having the participant. This is a fun, simple, kid friendly project requiring very few materials which demonstrates the concept of electrical resistance. With a 3.3v output voltage for the board, a safe amount of resistance to control current through an led. The hard graphite, from hb to 2h is brittle and will fracture if subjected to uneven heat. Here is a really simple experiment in witch you will make a kind of potentiometer (variable resistor) out of a sheet of paper and a graphite pencil (lead pencil). • calculate the resistivity of graphite and compare it to the known value • graphically demonstrate the dependence of resistance on the. A common experiment for pin output is powering an led. Burning pencils takes a little practice: Place the pencils on your garden grill with 1 cm apart. As most pencils are made of graphite, which is conductive, as the students draw lines on papers they are basically drawing imperfect. Using the ohmmeter, measure the electrical resistance of the graphite in the pencil by applying the probes to the exposed graphite at the ends.
