Question

Find the energy in kWh consumed in 10 hrs by four devices of power 500 W each.​

Answer 1

$Power = 500 \\ W= 0.5 \: kW$

$Time = 10 \: hours$

$Energy \: Consumed \: by \\ 4 \: Devices , \\ E=4×P×t$

$E = 4×0.500×10 \: kWh$

$E = 20 \: kWh$

Answer 2

Answer:

20 kWh

Explanation:

Because the rating of the powered device which is "p" equals 500 W which then equals 0.50 kW and "t" stands for the amount of time the device is running for so t=10 h the equation to figure out the amount of energy consumed by an electrical device is P = W/T so the energy consumed equals power × time so that means the energy consumed would equal

0.50 × 10 and that equals 5 kWh so the energy consumed by four equally rated devices in 10 h will create the equation of 4 × 5kWh which gives you your final answer of 20 kWh.
