1.	Insulators making rubbing contact require _______(a) Low conductivity(b) High conductivity(c) Low pressure(d) High pressureThis question was posed to me by my school teacher while I was bunking the class.This interesting question is from Classification of Lubricants in division Lubricants of Applied Chemistry
Answer» Right option is (a) LOW conductivity The BEST I can explain: Insulators making rubber contact NEEDED low ELECTRICAL conductivity. In some other applications of the solid LUBRICANTS, the high electrical conductivities. Sliding electric contact requires high electrical conductivity.
