ELECTRICAL CONDUCTIVITY OF GRAPHITE

Category: Electronics

Model No:SP-EC-GPH

In this experiment, length and cross-sectional area of the pencils tested will be kept constant. Thus, the resistance recorded should be proportional to the resistivity due to the chemical composition of the circuit component. 

Product Description

In this experiment, length and cross-sectional area of the pencils tested will be kept constant. Thus, the resistance recorded should be proportional to the resistivity due to the chemical composition of the circuit component. 

Setup Consists of the following: 

  • DC Power supply
  • Rheostat
  • Sample assembly
  • Graphite Rod
  • Connecting Wires

Scope of Learning:

1.    Determine the resistance of a graphite rod.
2.    Determine the resistivity of a graphite rod.
3.    Find the voltage at several points along the graphite.
4.    Gain an understanding of resistance, resistivity, current, and voltage.
