1000 watt electric heater is used everyday for 90 minutes ETA will consume units of electricity in 30 days
Answers
Answer:
load=800 watt.
Running hours per day= 6 hours
Daily consumption= 6 X 800= 4800 watt hour or 4.8 Kwh
Rate per unit= 3 Rs.
Daily Cost = 4.8 X 3= 14.4 Rs.
Monthly Cost= 14.4 X 30 = 432 Rs
The units of electricity consumption will be 30 units.
Given data :
Wattage of the electric heater is 1000 watt = 1 kilowatt [ Term of unit conversion is 1 kilowatt = 1000 watt]
Everyday running time is 90 minutes.
Total number of days is 30.
• At first we have calculate the total time of usage
= Usage time in one day × total days
= 90×30
= 2700 minutes
= 45 hours
• Now,
In 90 minutes the consumption = 1 kilowatt
In 1 minutes the consumption = 1/90 kilowatt
In 60 minutes the consumption = 60/90 = 2/3 kilowatt
In 1 hour the consumption = 2/3 kilowatt
In 45 hours the consumption = 2×45/3 = 30 kilowatt.
Now,we know that
1 kilowatt consumption is known as the 1 unit of electricity consumption.
So,the 30 kilowatt consumption will be 30 units of electricity consumption. (Answer)
