The dial of electronic watt hour meter is marked with the words "3200imp / kW · H" (IMP / kW · H "is an important parameter of electronic watt hour meter -" pulse output "unit, and its value represents the number of times that the power consumption indicator on the dial of 1kW · h consumes electricity). When an electrical appliance is connected to the meter alone and works for 20min, the indicator of the watt hour meter flashes 320 times, and the energy consumption of the electrical appliance in the above time The electric energy is______ KW · h, the electric power of the electric appliance is______ W. The maximum power of the electronic watt hour meter is______ W．

The dial of electronic watt hour meter is marked with the words "3200imp / kW · H" (IMP / kW · H "is an important parameter of electronic watt hour meter -" pulse output "unit, and its value represents the number of times that the power consumption indicator on the dial of 1kW · h consumes electricity). When an electrical appliance is connected to the meter alone and works for 20min, the indicator of the watt hour meter flashes 320 times, and the energy consumption of the electrical appliance in the above time The electric energy is______ KW · h, the electric power of the electric appliance is______ W. The maximum power of the electronic watt hour meter is______ W．

Because every 1kW · h of electric energy consumed in the circuit, the indicator flashes 3200 times. So when the indicator flashes 320 times, the consumed electric energy is: w = 320imp, 3200imp / (kW · h) = 0.1kw · h, and ∵ t = 20min = 13h ∵ the rated power of the electric appliance is: P = wt = 0.1kw · h13h = 0.3kw = 300W, and "220V" represents the rated voltage of the electric energy meter, "10A" represents the calibration current of the electric energy meter, and ∵ electric energy meter The maximum power in normal operation is: P = UI = 220V × 10A = 2200W, so the answer is: 0.13002200

2400r / kW

It means that the line consumes 1 kilowatt hour and the watt hour meter turns to 2400

Xiaoqiang's electric energy meter is marked with "2500r / kW · H", so how much J of electric energy is consumed when the dial turns one turn

2500r / kW · h means 1 kwh is consumed for 2500 revolutions, so 1 / 2500 kwh is consumed for each revolution
1 kwh = 1000W * 3600s
=3600 000J
So a turn consumes electricity
=3600 000J÷2500
=1440J

The electronic single-phase watt hour meter has been widely used, and its important parameter imp / (kW · h) indicates the number of times that the indicator light flashes when the power consumption is 1kW · h. Xiaoming's watt hour meter indicates "6400imp / (kW · h)". When an electrical appliance is connected to the meter alone, the indicator light flashes 640 times after the electrical appliance works normally for 5min, then the electrical energy consumed by the electrical appliance within 5min is______ The rated power of the appliance is______ W．

Xiaoming's electric energy meter is marked with "6400imp / (kW · h)". When an electric appliance is connected to the meter alone, and the indicator light flashes 640 times in 5min, the electric energy consumed by the electric appliance is 6400kw · H = 0.1kw · h; the rated power of the electric appliance is P = wt = 0.1kw · H = 1200W; so the answer is: 0.11200
