By using yin and yang (or fuinjutsu), the user applies this to their electrical powers. Usually used (in the case of Yin and Yang) for the creation of new ninjutsu, in a sense more yin and yang chakra is added to the nature for special and additional effects usually associated with the specific kinds of energy. While usually it is used for more physical effects, the electricity can be given more conceptual and spiritual properties too, but at a stronger price of chakra, even for a Lightning Master. In the case of using fūinjutsu (in lieu of yin-yang), it acts like a code to change the lightning's properties based on the symbols used. In a sense, Transcription Seals (and seals similar to the Strength of a Hundred Seal or Generic Sealing) could be added to lightning nature or electric charge
