How much electricity does a 1200W electrical appliance consume per hour?

How much electricity does a 1200W electrical appliance consume per hour?

1 degree = 1 kWh
So 1200 * 1 = 1200 watts per hour
So it's 1.2 degrees

How much electricity does 800 watts consume per hour,

One kilowatt hour is actually one thousand watts per hour, that is, one kilowatt hour is consumed by a 1000 watt electric appliance
W = Pt, where p with meter power, in kilowatts; t for time, in hours
800 = 0.8kw
So: P = 0.8 kW, t = 1 hour
So: the power consumption, w = 0.8 kW / h, is 0.8 degree

How many w electrical appliances need to use how much ah current? For example, 1000W needs 1000ah?

How many w electrical appliances need to use how much ah current? For example, 1000W is 1000ah? For AC, there is no such problem. For DC, ah is the capacity, which is related to the service time. For example, for 12V / 100W electrical appliances, if 12V / 20Ah battery is used, the service time is about 2 hours. If the battery capacity is doubled, the service time is about 2 hours, The time can be doubled, that is about 4 hours
