We know that power consumption or Energy is
E = Power x Time
for utility billing, we used
E = kWatt x Hour
But I am not sure how to get the total Energy if we will based it per second having different power over a period of time.
0.5 Watt (time check 5:00:00 AM) 1.0 Watt (time check 5:00:04 AM) 0.7 Watt (time check 5:00:07 AM) and so on.
Let say I wanted to calculate the energy from 5:00:00 AM - 5:00:07 AM
Is this the right calculation?
E1 = 0.5 x 4 = 2.0 Watt-sec E2 = 1.0 x 3 = 3.0 Watt-sec E3 = 0.7 x 1 = 0.7 Watt-sec E1 + E2 + E3 2 + 3 + .7 = 5.7 Watt-sec = .00158 Watt-Hr
I just want to know if my calculation is right. Thanks
