Power of each device, P=500 W=0.5 kW
Time for which the devices are used, t=10 hours
Thus energy consumed by 4 devices, E=4×P×t
E=4×0.500×10 kWh
⟹E=20 kWh

Answer:
the answer is 9 × 10^6
Explanation:
we know that
P = W ÷ t
from above we can write
W = P × t
by putting values
W = 250 × 10 × 3600 convert time to sec
W = 9 × 10^6
