In short, the 60 watt bulb has more resistance.
Power can be calculated using the following formula: P = (V^2)/R The power rating for a light bulb is measured using a 120 Volt source. Since the voltage will be the same for both light bulbs, using the formula, the bulb with the lowest resistance would have the greatest power.
Hence 100 watt bulb has less resistance.
