In the context of faraday s induction law, we show that the concept of virtual work provides another point of view to clarify the nature of the induced electric field, as well as the fact that the. The mass of different substances liberated or deposited by the same quantity of electricity is proportional to the atomic masses divided by the valencies of their ions. It states that, when the same quantity of electricity is passed through different electrolytes, the masses of different ions liberated at the electrodes are directly proportional to their chemical equivalents equivalent weights.
