Explanation:

This is an elementary problem, you know that

1. the lower wattage bulb will have higher resistance.

2. both bulbs in series will have the same current.

3. power is I^2 *R, so the bulb with the higher resistance ( the 60watt bulb ) will have more power so it will dissipate more heat and glow higher than the 100w bulb.

I THINK IT WILL HELPS YOU
