You probably worded your question wrong, since the answer would be 40w. But I'll work out the charge to run it for you.
I am working your questions using the MELBOURNE, Australia power tariff (charge) which is 17.000c per kw/h.
It takes roughly 25 hours for your 40w fluoro tube to consume 1 kilowatt of power, so the power consumption per hour would be around 0.0068 cents an hour.
Please take note of other amounts of electricity that have to be used in order to fire up your tube though, as some starter capacitors can use a big amount of energy (this is the reason why it is not recommended to use fluoro bulbs on 12v/24v - 240v/110v inverters). So basically, if you are going to be out of the room for less than 1 hour, leave it on.

What size amp circuit breaker do you use on a 55 watt fluorescent light?
A 55 watt fluorescent light only pulls 0.4 amps. Lights can be installed on a 15 amp breaker using 14/2 wire. A maximum of 1440 watts is all that is allowed on a 15 amp circuit.
How many amps in a small table lamp?
A 120 volt table lamp with a 75 watt bulb will pull 0.625 amps. With a 100 watt bulb it will pull 0.833 amps. And with a modern fluorescent 13 watt bulb it will pull 0.108 amps.
What unit is used to express electrical power?
Electrical power is also measured in Watts.
How many amperes does a 20 watt compact fluorescent lamp draw?
To answer this question the voltage has to be given. I = W/E. Amps = Watts/Voltage.
What parameters you consider when you calculate the current consumption of a 40 watt fluorescent bulb?
voltage, current and power factor
What is deferent 60 watt to 3 froucent bulb?
If you are comparing the energy consumption of a 60-watt incandescent bulb to three 20-watt fluorescent bulbs, the fluorescent bulbs will consume less energy overall. Each fluorescent bulb uses less power than the incandescent bulb, resulting in a lower total energy consumption when all three are used together.
Can you use 40 watt in a fluorescent light in place of a 32?
Yes, the wattage is just the power consumption. A 30 watt Fluorescent will give more or less the same light as a incandescent bulb or 60 watts, which is the limit for your fixture for incandescent bulbs.
How much electricity does a 33 watt fluorescent tube consume per hour?
A 33 watt fluorescent tube consumes 33 watt-hours of electricity per hour. It means it uses 0.033 kilowatt-hours (kWh) of electricity in one hour.
What is the maximum power consumption of a 120 watt bulb?
The maximum power consumption of a 120 watt bulb is 120 watts.
Can you replace a 32 watt fluorescent with a 40 watt fluorescent?
?
How much money does 40 watt 4ft fluorescent tube use a year?
To calculate the annual cost of running a 40-watt 4ft fluorescent tube, you need to know the cost of electricity per kilowatt-hour in your area. Usually, a 40-watt fluorescent tube is on for about 8 hours per day, so you would multiply the wattage (40) by the hours/day (8) to get watt-hours per day. Convert that to kilowatt-hours and then multiply by the number of days the light is on per year. Finally, multiply that by the cost per kilowatt-hour to get the annual cost.
How many kWh will a 32 watt fluorescent bulb use?
A 32 watt bulb uses 32 watt-hours, or 0.032 kWh, every hour it is used.
What is 800mW?
800 milliwatts, or 0.8 watt. It's a measurement of output power or power consumption.
ONE electrical unit of power equals how many watt?
A unit (short for 'Board of Trade Unit') is used to measure energy consumption, and is equivalent to one kilowatt hour. A watt measures power, which is the rate of energy consumption. So there is no relationship between a unit and a watt.
How many 75 watt fluorescent bulbs are needed to give as much light as a 75 watt incandescent bulb?
A 15-watt fluorescent should produce about as much light as a 75-watt incandescent.
What is the conversion factor from lux to watt and how can it be used to determine the power consumption of a light source in terms of lux?
The conversion factor from lux to watt depends on the efficiency of the light source. It can be used to determine the power consumption of a light source in terms of lux by multiplying the lux value by the conversion factor to get the power consumption in watts.
