About This Product
Altering the length and diameter of a putty cylinder in simple multiples lets the dependence of resistance on length and cross-sectional area be established quickly. Coins or washers placed on the ends connect it into a circuit. Besides buyers across India, the Conducting Putty - 100g can be exported to institutions in Slovenia, Mongolia, Suriname, United States, Comoros and Libya.
Frequently Asked Questions
Q1. What resistance does a cylinder have? A cylinder 60 mm long and 20 mm in diameter has a resistance of about 20 Ω.
Q2. Is the putty safe to handle? The substance is harmless but messy, so plastic gloves are supplied for handling it.
