Если выстрелить из мелкокалиберной винтовки в варёное яйцо, то в яйце образуется отверстие. Если выстрелить в сырое яйцо, то оно разлетится. Действие какого закона иллюстрирует второй пример? Сформулируйте этот закон.

Yes that is Russian if that is what you are asking

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
