Answer 2

Answer:

12500 Joules is the required energy.

Given:-

Time taken ,t = 10 h

Number of Devices ,n = 5

Power of each device ,P = 250 W

To Find:-

Energy Consumed by Devices,E

Solution:-

As we have to calculate the Energy Consumed by devices in 10 hours .

Energy is defined as the Product of Power and Time.

• E = P× n × t

Where,

P denote Power of device

n denote number of devices

t denote time

Substitute the value we get

→ E = 250×5 × 10

→ E = 1250 × 10

→ E = 12500 J or 12500 Wh = 12.5 kWh

Hence , the energy consumed by the devices is 12500 Joules .
