Find the energy consumed in 10 hours by 5 devices of power 250 W each.
Answers
Answer:
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 .
Answer:
power consumed by one device=250watt
power consumed by five devices=250×5 =1250 watt
time taken =10 hours
energy=power×time
energy consumed =1250×10
=12500J
