千瓦时
...电功率怎么求几度电给了电功率怎么求几度电把电功率P的单位换算成千瓦KW,时间单位换算成小时h,用公式W=Pt计算出多少千瓦时(KWh)就是多少度电.
千瓦小时
电能的计量单位是kWh(千瓦小时),1千瓦小时等于一度电,意思是1千瓦的用电器工作1小时,消耗的电能(电量)就是一度电,30kw工作1小时就用30度电,工作2小时就用...
度电
...零后,又开了A公里,车载电脑记录,在这期间你总共消耗了B升汽油(依靠电喷油量计得),在这期间你还靠外插220充入过C度电(KWh),同时你还把这C度电都用完了。
电能
有功电能(Kwh):有功电能是有功功率对于时间的积分。以Kwh为单位。
The kilowatt hour (symbol kWh, kW·h, or kW h) is a unit of energy equal to 1,000 watt-hours, or 3.6 megajoules. If the energy is being transmitted or used at a constant rate (power) over a period of time, the total energy in kilowatt-hours is the product of the power in kilowatts and the time in hours. The kilowatt-hour is commonly used as a billing unit for energy delivered to consumers by electric utilities.
