Question

9.
Find the energy consumed in 10 hours by 5
devices of power 250 W each.
Guys please answer these question...​

Answer 1

Answer:

Energy = Power × Time

E = P×T

E= 250W×10hrs

E= 2500

E=2500/1000

E=2.5 KWh

Answer 2

Explanation:

• 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 .
