Solution

To find the energy consumed in kWh, we can use the formula:

Energy (kWh) = Power (kW) x Time (hours)

First, let's convert the power of each device from watts to kilowatts:

Power (kW) = Power (W) / 1000

For each device, the power is 500 W, so:

Power (kW) = 500 W / 1000 = 0.5 kW

Since there are four devices, we need to multiply the power by 4:

Total Power (kW) = 0.5 kW x 4 = 2 kW

Now, we can calculate the energy consumed in kWh by multiplying the total power by the time:

Energy (kWh) = Total Power (kW) x Time (hours)

Given that the time is 10 hours:

Energy (kWh) = 2 kW x 10 hours = 20 kWh

Therefore, the energy consumed in 10 hours by four devices of power 500 W each is 20 kWh.
