The rated current marked on Xiaoming's watt hour meter is 10a, so the sum of the rated power of various electrical appliances allowed to be connected to the watt hour meter is 10A______ W.

The rated current marked on Xiaoming's watt hour meter is 10a, so the sum of the rated power of various electrical appliances allowed to be connected to the watt hour meter is 10A______ W.


The voltage of the home circuit is 220 V, according to P = UI: the sum of the rated power of various electrical appliances allowed to be connected to the meter is p = 220 V × 10 a = 2200 W; so the answer is: 2200 W
