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 instrument measures electrical power?
The Ammeter XD
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
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.
Can you replace a 32 watt fluorescent with a 40 watt fluorescent?
?
Which among the following is most energy efficient incandescent build fluorescent tube compact fluorescent light bulb halogen bulb?
Incandescent produces about 10 lumens of light per watt of electricity Halogen produces about 13 lumens per watt Fluorescent and CFL produce about 50 lumens per watt So Fluorescent is the most efficient.
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.
Can 32 watt t12 fluorescent lamps be used where a 40 watt t12 fluorescent lamp was used?
Yes, these lamps can be interchanged.
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.
Power is measured in?
Watts.Power is measure in Watt.Power consumption is measure in WH (Watt Hour).

How many watts fluorescent tube?
The answer is 40 watts, power is a rate of energy. If you are looking for the total amount of energy it uses over its life, take its expected life and multiply it by 40 watts, which will give you your watt-hours. For example Expected life of the bulb is 2000 hrs Then it would be 2000*40 = 80,000 watt - hours or 80 KW-Hours Power companys charge by the KW hour used
What will 2 kilowatts power?
Two irons or a 2-kW room heater, or about thirty 60 watt lights, or about a hundred and thirty 15-watt compact fluorescent bulbs.
