当你取出一块冷冻华夫饼饼放进烤面包器时，电能转化成了热能。

Just as electricalenergy generates heat when it meets resistance so our psychic energy generates tension and stress when it has to flow through areas that aren't our preference.
就像电子遇到了电阻时能量产生热量那样，当我们的心理能量流向不喜欢的领域时，我们就会产生紧张和压力。

The major difference between these two power generators is that the chemical energy of the fuel cell is converted directly to electrical power without intermediate conversion first to heat.
