电能表是用来测量电功的仪表,也就是测量电路消耗电能的仪表常见的电能表的表头及铭牌如图所示.表头及铭牌可提供给我们一些信息,解决相关的问题.一、测量电路消耗的电能电能表测电能的方法有两种:1.由表头中的数字直接读出要测量某一时段消耗的电能,只要将这一时段前后两个时刻表头上的读数相减.其差值即为该时段内电路消耗的电能.
Electric energy meter is used to measure the electric power meter, which is the meter that consumes electric energy. The header and nameplate of a common electric energy meter are shown in the figure. The header and nameplate can provide us with some information to solve the related problems. Measuring the power consumed by the circuit There are two ways to measure the power: 1. Read directly from the number in the meter to measure the power consumed during a certain period of time. Subtraction. The difference is the electrical energy consumed by the circuit during this period.
