What current does the electric water heater normally work on?
According to Q=U*I*T, Q, that is, the current done in 100min (B-A), U=220V, T=100min=6000 seconds,You can find the I
The power P= voltage is multiplied by the current (UI)Both I=P/U, China, home voltage are 220V. So it's easy to get down.100 minutes, =1.666 hoursDegree difference =2.5KW2.5/1.666=1.50KW=1500W1500W /220v=6.818 (A)
The formula is too crude, I come to the actual. Kilowatt hour per kilowatt hour. 1KW's power consumption was 1 hours!Seek the current, the first power.B-A = the amount of electricity used by the electric water heater.Here are some examples:It used 1.5 kwh in an hour. 1.5/1=1.5KW, then it's 1500W's.,Half an hour with 1.5 degrees, 1.5/0.5h=3KW, or 3000W2 hours, 1.5 degrees, 1.5/2h=0.75KW, or 750W
