Galvani discovered that the frog muscle contracts by applied electrical potential. Yours is not very different from the frogs. So your muscle should vibrate with twice the frequency of the home power. Electricity shows you are not different from a frog. ========================= why muscle vibrate with twice the frequence of the home power? ^^ |
