What is Conductors and insulators
Conductors - one or more electrons from each atom in solid can move freely by body conducting electric charge (metals)
Insulators - electrons are strongly bound to nuclei inhibiting electric charge (plastics, rubber, and glass)
Working: When plate potential (V p ) is positive, plate current ( I p ) flows in the circuit (because some emitted electrons reach to plate). If + V p enhances I p also increas
