There is 3000r / kW. H on the dial of an electric energy meter. Use the electric energy meter and stopwatch to calculate the electric power of an electric lamp and let the lamp work independently, It takes three minutes to find out: (1) what is the electric energy consumed by the lamp? (2) the electric power of the lamp

There is 3000r / kW. H on the dial of an electric energy meter. Use the electric energy meter and stopwatch to calculate the electric power of an electric lamp and let the lamp work independently, It takes three minutes to find out: (1) what is the electric energy consumed by the lamp? (2) the electric power of the lamp

(1) Power consumption = (15 / 3000) = 0.005kw. H
(2)0.005/(3/60)=0.1KW=100W

The electric energy meter of a family circuit is marked with 3000r / kW. H. now I want to use the meter to measure the electric power of a bulb
The electric energy meter of a family circuit is marked with 3000r / kW. H. now I want to use the meter to measure the electric power of a bulb. The bulb lights up normally after it is powered on. The turntable of the meter turns 10 revolutions in 2min
(1) How much work does the current do?
(2) What is the rated power of this light bulb?

Rated power of this bulb:
P＝10/2×60/3000＝0.1(KW)＝100W
