1. 电能：首先要明白,所有电池储存的系化学能(chemical energy) 而非电能(electrical energy),电池放电时将化学能转化成电能.而差电机的作用就系将电流方向逆转(所以差电电压一定要高过电池的电压),从而将电池内的化学物质还原,

2. 电能;电力：electrical cut-off switch 电力截断掣 | electrical energy 电能;电力 | electrical plug 电插头

3. 导电率：电器 electrical conductivity | 导电率 electrical energy | 电能 electrical meter

4. 电能=電気：electrical endurance == 电气耐久性 | electrical energy == 电能=電気エネルギー | electrical engineer == 电气工程师

noun

1. energy made available by the flow of electric charge through a conductor

e.g. they built a car that runs on electricity
