(111) Calculate electricity bill for ONE month in a house which is using electrical devices as follows,
Unit rate is RS. 3/-
(a) One 60 W bulb is used daily 6 hours
(b) A Fridge of 120 W is used 24 hours a day
(c) TV of power 150 W is used 5 hours a day
Answers
Explanation:
ANSWER:359.1 Rs
your question answer is
Bulb = (60/1000) X 1X 6 = 0.36 units
fridge= (120/1000) X 1X 24= 2.88units
TV = (150/1000) X 5 = 0.75 units
Total power consumed = 0.36+ 2.88 + 0.75 = 3.99 units
electricity cost = 3.99 X 3 X 30 =Rps.359.1 for 30 days
Explanation:
You can calculate the electricity cost using below step
Find out the watts each electronic device uses per day.
Now Convert watts to kilowatts. (1 watt = kilowatts/1000)
Find out the kilowatts an electronic appliance uses per month.
Now Finally find out the electricity cost.
Calculate the Energy consumption per day using below formula
E(kWh/day) = P(W) × t(h/day) / 1000(W/kW)
Calculate Electricity cost per day using below formula
Electricity Cost($/day) = E(kWh/day) × Cost(cent/kWh) / 100(cent/$)
