CONDUCTIVITY PUTTY

CONDUCTIVITY PUTTY

•  A versatile aid for the teaching of resistivity and the dependence of resistance on the length and cross sectional area of a conductor.
•  This 100g Conductivity Putty cylinder pack is 60mm long x Ø 20mm and has a resistance of 20-Ohms.
•  In senior level the conductivity putty can be used to show how the capacitance of a sphere varies with the radius by using a digital coulomb meter.

(Wikipedia excerpt: .."...Conductive polymers or, more precisely, intrinsically conducting polymers (ICPs) are organic polymers that conduct electricity.[1][2] Such compounds may have metallic conductivity or can be semiconductors. The main advantage of conductive polymers is that they are easy to process, mainly by dispersion. Conductive polymers are generally not thermoplastics, i.e., they are not thermoformable. But, like insulating polymers, they are organic materials. They can offer high electrical conductivity but do not show similar mechanical properties to other commercially available polymers. The electrical properties can be fine-tuned using the methods of organic synthesis[3] and by advanced dispersion techniques.[4] ...")
