RVFM Conducting Putty

Conducting putty is a useful aid to teaching resistivity and the relationship between length and cross-sectional area on resistance. Can readily be connected into an electrical circuit and both length and diameter can easily be altered by re-moulding the putty. Although harmless, plastic gloves are provided to prevent hands from becoming stained.
