How many watts is AC 220 V 50 Hz? I want to see how many watts of power supply, but it only says AC 220 V 50 Hz. How many watts of power supply is this? It is pasted with yellow paper, and then nothing is written! My configuration is e2140 p5gc MX plus 8500gt maverick 160g 1G memory. I think it should be 350W or 330W?

In short, the data you write on it has no way to judge the power,
ac 220V 50Hz
Refers to the AC 200 V, 50 Hz, that is, we usually lighting power supply voltage and frequency, there is no way to you want to know the power!
In fact, from a physical point of view,
Power P = V (voltage) Xi (current)
Therefore, you can't know the power just by the data you said. If you look back, you can send baidu information to me, and I'll tell you!
Good luck!



The dial of electronic watt hour meter is marked with 3200imp / kW · h. an electric appliance is connected to the meter and works normally for 30min
The indicator light of the electric energy meter flashes 320 times. How many kilowatt hours of electric energy is consumed in the above time


Power consumption w = 320imp / (3200imp / kW · h) = 0.1kwh



The dial of an electric energy meter is marked with "3200imp / (kW · h)", and the electric appliance is connected to the meter separately. When the electric appliance works for 5min, the indicator light on the electric energy meter flashes 160 times. If the rated voltage of the electric appliance is 220V, the electric energy consumed by the electric appliance should be used instead


3200imp/(kW·h)
 
imp
 



(Junior High School Physics) the dial of electronic energy meter is marked with 220V 10A 3200imp / kW · H
The dial of electronic watt hour meter is marked with 220 V 10A 3200 imp / kW · H (IMP / kW · h, the value indicates the number of times that the power consumption indicator on the dial of 1 kW · h flashes). When an electrical appliance is connected to the watt hour meter alone and works normally for 30 minutes, the indicator of the watt hour meter flashes 160 times, and the energy consumed by the electrical appliance in the above time is____ J. What is the actual power of an electrical appliance____ W.


1,
W/1kWh=160/3200
W=0.05kWh
=0.05*3.6*10^6
=1.8*10^5J
2,
P=W/t
=1.8*10^5/1800
=100W
