What is the difference between emf and galvanic Series?
Definition:
EMF: Electromotive force (EMF) = terminal potential difference when there is no current flowing. EMF and terminal potential difference (V) are not the same even though they are both measured in volts. The EMF is the amount of energy (E) provided by the battery for each coulomb of charge (Q) passing through (ϵ).
Galvanic Series: The electrochemical potential and nobility of metals and metal alloys are determined by the galvanic series.
EMF Series | Galvanic Series |
1 .The EMF series is prepared by the salt solution of that element | 1. It is prepared of solution |
2. Only pure metals are used to prepare it | 2. Both metals and alloys can be used in its preparation |
3. It is quantitative | 3. It is qualitative |
4. It assumed the theoretical calculations | 4. It is used for practical calculations |
5. It can works only in certain standard conditions | 5. It works in any normal condition |
