Question

A sign built with eight fluorescent 40-watt lamps remains on for 10 hours a day, and the energy use cost per kWh is 19 rupees
what is the calculation of amount for 365 days per year

Answer 1

The calculation

-->8 lamps X 40 watts each = 320 watts;

To convert watt to kilo watt

divided by 1,000 = 0.32 kilowatts;

multiplied by 10 hours = 3.2 kWh;

multiplied by 0.19×3.2 = 0.61Rs is per day amount

multiplied by 365 days = 221.92Rs per year.

If the sign ballast were the magnetic type,

then the per-year cost = 3.2 X 365 X 1.15 X 0.19 = 255.21 rupees

Hope it's helpful to you
