Good and Bad Conductor of Electricity
Product Code : SCL-EAE-11200
Quick answer: The Good and Bad Conductor of Electricity apparatus is a low-voltage test circuit for sorting materials into conductors and insulators. A sample is placed across the test contacts; if it conducts, the circuit closes and the indicator responds, and if it insulates, there is little or no response. Lab Exports manufactures it in Delhi for schools.

How the conductor test is done
A material is a good conductor when it has many free charge carriers, as metals do, and a poor conductor or insulator when it has very few, as with plastic, rubber, glass, dry wood or paper. Placing each sample in the gap of a simple circuit turns this idea into a direct observation.
- Check the circuit by touching the two test contacts together; the indicator should respond.
- Place a sample firmly across the test contacts.
- Note whether the indicator responds fully, weakly or not at all.
- Repeat with each sample and record the results in a conductor and insulator table.
Metals such as copper, aluminium and iron make the indicator respond, while plastic, rubber, glass and dry wood do not. Graphite from a pencil is a useful extra sample because it is a non-metal that conducts.
