The power *P* in watts (W) is equal to the energy *E* in watt-hours (Wh)
divided by the time period *t* in hours (h):

*P*_{(W)} = *E*_{(Wh)} /
*t*_{(h)}

So

Watts = Watt-hours / Hours

or

W = Wh / h

Find the power consumption in watts given an energy consumption of 15-hours and a time duration of 3 hours.

*P* = 15 Wh / 3 h = 5W
