1度电等于多少千瓦时?
1度电等于1千瓦·时。
1、瓦特是功率的单位,而度是电功的单位,它们之间不能相互转换。但一度电与千瓦时则是可以互换的,对于日常来说,简而言之,1千瓦时即1度。
2、千瓦时就是平时所说的“度”,是电功的单位。瓦特是功率的单位。如果在功率上再乘以一个时间,那么这个结果就是功。
3、电功率表示消耗电能的快慢,1千瓦时的物理意义是功率为1kW的电器工作1小时所消耗的电能。
4、1度电=1000wh(瓦·时) 意思是一度电可以让功率为1000瓦的电器工作一小时。 电磁炉以更大功率2000W,连续工作半个小时就会耗电一度。
一度电是多少千瓦时?
一度电就是1000瓦时,相当于功率1000瓦的设备一小时的耗电量。所以设计经常看电器标多少W或者kw来看设备的功率,这个是一个衡量值。
一度电等于多少千瓦时
一度电等于1千瓦时。
千瓦时就是平时所说的“度”,是电功的单位,符号:kW·h,计算公式为功率乘以时间。假设一台耗电设备的功率为2500瓦,即其一小时的耗电量为2.5千瓦时,也就是一小时2.5度电。
扩展资料:
功的单位有焦耳和千瓦时,它们之间的关系如下:
1焦=1瓦×秒
1千瓦时=1千瓦×1小时=1000瓦×1小时=1000瓦×3600秒=3600000焦
即:1千瓦时=3.6×10^6焦
1kW.h=1kW×h=1000W×h=1000W×3600s=3600000J
电功率的公式:P=W/t
(公式中的t表示时间,基本单位为秒-s,也常用单位小时-h来作计算)
电功率的测量公式:P=UI
(公式中的U表示电压,基本单位为伏特-V;大写I表示电流,基本单位为安培-A)
根据欧姆定律:U=IR
(公式中的R表示电阻,基本单位为欧姆-Ω)
