Answer:
11680 cents
Explanation:
The computer turned on 8 hours per day.
So, In 365 day the computer turn on 2920 hours (365*8 hours).
Power P = 400 W
the consumption of energy,
E = Pt
E = 400*2920
E = 1168 kWh
Now, electricity cost is 10 cents per kWh.
So, for 1168 kWh the electricity cost is 1168*10 = 11680 cents.
Hence, the electricity cost in 365 days is 11680 cents.
The total cost depends upon the amount of the electric current utilized in the given time. The total cost to run the computer annually will be 11680 cents.
What is power?
Power is said to be the rate of doing the work. Its' si unit is the watt. Horsepower is another unit of power. Mathematically it is given by the total work done to the total time taken by the body.
The given data in the problem is;
P is the power = 400-W
The cost per Kwh= 10 cents
t is the time utilization in one day= 8 hours
The expenditure is found as;
[tex]\rm P= \frac{E}{t} \\\\ \rm E = Pt \\\\ \rm E = Pt \\\\ \rm E = 400 \times 2920 \\\\ \rm E= 1168 Kwh[/tex]
The total value of cost = 1168 ×10= 11680 cents
Hence the total cost to run the computer annually will be 11680 cents.
