Assume the rating of 100W refers to operation on a supply of 117 volts.Power = (voltage) x (current)Current = (power) / (voltage) = 100/117 = 0.855 ampere (rounded)Power = (voltage)2 / (resistance)Resistance = (voltage)2 / (power) = (117)2 / 100 = 136.89 ohms
The formula you are looking for is E = W/I.

The 25w bulb, since it has the much higher resistance. The resistance can be derived from:P = V^2/RR = V^2/PFor the 100w bulb:R = 220^2/100 = 484 ohmsFor the 25w bulb:R = 220^2/25 = 1936 ohmsWhen connected in series, and then connected to 440V, the voltage across the 100w bulb would be:V = 440*484/(484+1936) = 88VThis is well within spec.The voltage across the 25w bulb would be:V = 440*1936/(484+1936) = 352vThis is way over spec, and would cause the bulb to fuse.Although this answer assumes that a light bulb is a linear resistor, they are not. The resistance of a light bulb changes significantly with voltage and filiament temperature. The 25w light bulb is still the one that fuses, but the non-linearity of the resistance needs to be understood.
60 watt bulb shall illuminate first
In parallel, they both obviously have 220 v across them, so the 100 W bulb is obviously brighter than the 60 W one. The 60 W bulb has more resistance, and in series they both have to pass the same current, so the 60 W has more voltage across it and might be brighter.

The coordinates 60N 100W point to Canada. It is located in the northern part of the country, specifically in the province of Manitoba.
A tortoise has to be around 4 years when you upgrade your heat to a 100w.
100/w
It depends on the wattage of the toaster. If the toaster has a wattage greater than 100W, then it will use more electricity than a 100W light bulb. If the toaster has a wattage less than 100W, then the light bulb will use more electricity.
The coordinates 40N 100W point to North America, specifically to the central part of the United States.
