Step-by-step explanation:
1. Electro chemistry : Electrochemistry is the branch of physical chemistry concerned with the relationship between electrical potential, as a measurable and quantitative phenomenon, and identifiable chemical change, with either electrical potential as an outcome of a particular chemical change, or vice versa.
2. Conductor of electricity : physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge in one or more directions. Materials made of metal are common electrical conductors.
3.non _ conductors of electricity :Sulphur, Phosphorus, Wood are non-conductors of electricity due to no presence of free electrons in outermost shell.
4. Anode and eathode : Anode and Cathode are the two classifications in which electrodes are classified. The significant difference between anode and cathode is that at anode oxidation takes place. As against, at the cathode, reduction occurs.
