Watts= voltage times amps. So if you divide Watts by voltage, you will get amps = .33333 or about a 1/3 amp load. This is assuming a 120 volt circuit.
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.
To answer this question the voltage has to be given. I = W/E. Amps = Watts/Voltage.
The voltage isn't decided by the lamp, but by the supply the lamp is hooked up to.
No, the ballast has to be matched to the lamp. 250 watt ballast, 250 watt lamp. Also be sure to match the lamp type to the proper ballast even though the wattage is the same. HPS ballast to HPS lamp, Metal halide ballast to metal halide lamp and mercury vapour lamp to mercury vapour ballast.
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.
Yes, these lamps can be interchanged.

Providing the lamp is operating at its rated voltage, a 60-W lamp will require 60 W. Thought that should be self-evident!
A 15-watt fluorescent should produce about as much light as a 75-watt incandescent.
Apart from no, your question has no simple answer. Fluorescent lamps need a few kV to start them and have a 90V drop when running. All of that is provided by the "gear" needed to run a fluorescent lamp. In a compact fluorescent (CFL), the gear is inside the cap.
It depends on the voltage and whether the lamps are actually 40 watts or 40 watt equivalent. Watts / volts = amps
6 watt bulb for mini lamp
TWO
As long as the lamp holder will take the larger wattage lamp and the current of the circuit is sized to take the larger current then yes, the lamps should be interchangeable.
