24 hours 0.37 degree electricity, what is the power of this electric appliance


  P=W/t=(0.37×3.6×106j)/(24×3600s)=15.42w
It's the sixth power of 10. It can't be hit. Pay attention



How many watts is the power of 220 pairs of 1 a electrical appliances? How many kilowatts per hour?


Voltage × current = power
220×1=220(W)
One kilowatt hour is equal to one kilowatt hour
The electricity consumption of 220 watt electrical appliances in one hour is 220 △ 1000 = 0.22 (KWH)



What is the difference between 10hr and 20HR?
Is the discharge rate HR related to the battery capacity? For example, which of 12v9ah / 10hr and 12v9ah / 20HR is used longer? Is the smaller the value in front of HR, the more durable the battery is? Is 12v9ah / 10hr twice as durable as 12v9ah / 20HR?


The capacity of the battery is determined by the voltage and ampere hour. HR is the recommended discharge time. According to your example, the capacity of the two batteries is 12 * 9 = 108wh. But the discharge rate of the two batteries is different. The first one is 10hr, which means that in the case of continuous discharge, 108wh can be discharged after 10 hours, so the best utilization can be obtained



Capacity of "12V 24Ah" battery
This capacity means that the battery can discharge at 24 A for one hour
Does this "1 hour" mean that the battery discharges to 0 V or to 10.5 v?


There are usually two ways to define the capacity of a battery: one is the 10 hour system, and the other is the 20 hour system. The former means that when the battery discharges at a constant current for 10 hours, and the voltage just drops to 10.8V (1.8V / cell), The product of this current and 10 hours is the capacity of the battery in 10 hours mode; the latter is to extend the discharge time to 20 hours. For the same fast battery, the capacity defined by the latter is larger than the former
If the capacity of 12V 24Ah battery is defined by 20 hours standard (most batteries use this way to define the capacity, and the value is relatively large), it means that the voltage just drops to 10.8V when discharging with 5A current for 20 hours
There is no battery. The capacity is defined in one hour mode
