Yes. The resistance of a globe depends not only on the wattage of it but also on the voltage.
A 12 V Globe would has a quarter the resistance of a 24 volt globe for the same wattage. (when alight)

Will 60 watt bulb put out same wattage at 50 and 60 hz?
Most equate wattage with the amount of light a bulb will put out. But, the wattage is the result of the resistance of the element and the voltage and is the amount of heat. the frequency is unrelated.
How do you prove that it is the wattage and not the physical size of a light bulb that matters for energy use?
Energy use is measured in watts. The watts used by a light bulb is on the package or the bulb. Find bulbs with the same wattage but different physical sizes if you want to prove this.
Does a 25 watt light bulb draw more current than a 60 watt light bulb?
No, a higher wattage INCANDESCENT light bulb uses more current than a lower wattage INCANDESCENT light bulb. Some CF and LED bulbs are rated by the amount of light that an incandescent bulb would produce, but they are also rated by the wattage that they use.
How does the amount of magents and wire affect the brightness of a light bulb?
The brightness of a light bulb directly has no direct relationship with magnets and wire. The bulbs brightness is determined by the wattage of the bulb. The higher the wattage of the bulb the brighter the bulbs light output.
What is the power of a light bulb?
Every person has a different power of light bulb. In my room, I have a 7.5 and a whole bunch of 60s. The number of watts you choose for your light bulb depends on how bright you want your light to be. The higher the number, the brighter it is.

Does the size of the light bulb affect how much energy it uses with wire and a battery?
No, only the resistance of the filament counts (normally marked as "wattage" on the bulb).
For bulbs connected in series the high watt bulb has high resistance?
No, the highest wattage bulb will have the lowest resistance.

How does a light bulb's wattage affect the heat detected above a light?
the higher the wattage is the hotter it gets
How is the rating of a light bulb determined for instance 100W 60W is that how many watts an hour to run it?
No, the wattage is determined by the resistance of the filament in the light bulb. The formula to determine the wattage is Watts = Voltage (squared)/Resistance in Ohms. To find the resistance of a 120 volt light bulb use the formula, Resistance in Ohms = Voltage (squared)/Watts. So for a 100 watt bulb at 120 volts the resistance is 120 volts x 120 volts = 14400/100 = 144 ohms. For a 60 watt bulb at 120 volts the resistance is 120 volts x 120 volts = 14400/60 = 240 ohms. As you can see this holds true to Ohm's law, current is inversely proportional to the resistance of the circuit. The higher the resistance of a load, the harder it is for the current to flow. In this case less current results in less light being emitted from the filament in the light bulb.

Who invented light bulb wattage?
Thomas Jefferson
Does a light bulb's life depend on its wattage?
hu
What could you do to a closed circuit consistenting of a battery a light bulb and a switch that increase the amount of current?
To increase the current you either need to reduce the resistance of the load or increase the voltage. Typically a higher wattage light bulb will decrease resistance or you could put multiple batteries in series.
Three bulbs of different watts are connected in series - which bulb will burn brightly - the higher wattage bulb or the lower?
lower wattage bulb
