生:电功和电功率有什么区别和联系?师:电功与电功率有四大区别:1·电功与电功率所描述的物理概念不同:电功描述的是电流做功的多少,而电功率则描述的是电流做功的快慢。快慢的含意与大小的含意是不同的,电功只有多少没有快慢,电流做功多说明消耗的电能多;电功率不仅跟电流做功多少有关,还跟做功时间的长短有关,它是由上述两个因素决定的。也就是说做功多的物体功率不一定大,功率大的物体做功也不一定多。一个用电器的电功率大,等于它在1s内消耗的电
Student: What is the difference between electric power and electric power? Contact: There are four major differences between electric power and electric power: 1. Electric power and electric power Describe the different physical concepts: Electric power describes how much current does work, and electric power describes The current is the speed of doing work. Meaning of speed and meaning of the meaning of the size is different, only the number of no power speed, the current power to work more power consumption; power not only with the power to do much work, but also with the length of work time, it is from the above two factors decided. In other words, the power of objects that do more work is not necessarily large, and the power of large objects does not work much. The electrical power of an appliance is large, equal to the electricity it consumes within 1 s
