60 w bulb means it will take 60w power/second .
since 1hrs = 3600 second,
so total power consumed in 3600 sec = 3600*60w= 216000 watt = 216kw.
now since 1kwh = 1 unit of power = 1000w*3600=3600kw.
suppose we have to pay 10rupees for 1 unit.
means we have to pay 10 rupees for 3600kw
so for 216kw we have to pay 216/360=60paise=.60rupees
The bulb uses 7.5 watt-hours each hour, or 90 watt-hours if left on for 12 hours. 1 unit of electricity would be used in 11 days at 12 hours per day.
The cost of electricity for a light bulb being on for a long time depends on the wattage of the bulb, the electricity rate per kilowatt-hour, and the duration it is on. To calculate the cost, you can use the formula: (Wattage of bulb / 1000) * hours on * cost per kilowatt-hour.
To calculate the cost per hour to use a 150 watt light bulb, you would first need to know your electricity rate per kilowatt-hour (kWh). Once you have that, you can convert the wattage of the light bulb to kilowatts (0.150 kW) and multiply it by the electricity rate to determine the cost per hour. Keep in mind that rates vary depending on your location and energy provider.
A 100 w light bulb uses one tenth of a kilowatt of power, therefore in 1 hour it uses one tenth of a kilowatt-hour of energy, that is 0.1 units, or 1.5 p.
On average, a 32W T8 fluorescent bulb running 24 hours a day for 30 days at an average electricity rate of $0.12 per kilowatt-hour would cost about $7.84 per month.
A 0 Watt bulb does not consume electric power so the cost is zero.
That bulb is 100 watts or 0.1 kilowatts so it uses 0.1 kilowatt-hour of energy each hour, which costs about £0.015
The bulb uses 7.5 watt-hours each hour, or 90 watt-hours if left on for 12 hours. 1 unit of electricity would be used in 11 days at 12 hours per day.
Assuming an electricity rate of $0.12 per kilowatt-hour, running a 70-watt light bulb for 1 hour would cost $0.0084 or 0.84 cents. This calculation is done by converting watts to kilowatts (70W = 0.07 kW) and then multiplying by the cost per kilowatt-hour.

You have to have three factors to calculate this cost. First what you are charged per Kw/hr from your power supplier, second the wattage size of the bulb that you want to do the calculation on and third the voltage of the bulb. Give me these and I can tell you how it costs to run the bulb per hour.
Typical home energy cost is 10 cents per kilowatt hour A 60 watt bulb running for one hour uses 60 watt hours .10 X (60/1000) = .006 cents per hour 16.66 60watt bulbs on for one hour would cost 10 cents.
For the first hour the fuel burn is approx 6000 pounds @ 4 USD /Gallon (check actual price for jet fuel) = $3,529.41 USD/Hr (first hour) for fuel burn only!
A 100 w light bulb uses one tenth of a kilowatt of power, therefore in 1 hour it uses one tenth of a kilowatt-hour of energy, that is 0.1 units, or 1.5 p.
Depends on the bulb snowflake.
A 450-watt bulb consumes 450 watts of electrical power when it is turned on. If it operates for one hour, it will use 0.45 kilowatt-hours (kWh) of energy. The cost of running the bulb will depend on your local electricity rates, which are typically charged per kWh. For example, if the rate is $0.12 per kWh, running the bulb for one hour would cost about $0.054.
