When a (60W, 220V) bulb and a (100 W, 220 V) bulb are connected in series,
When a (60W, 220V) bulb and a (100 W, 220 V) bulb are connected in series, then which bulb will glow brighter?

The resistance of the bulb is given by R=(V2/P). So, the resistance of 60 W bulb is more than the resistance of 100 W bulb. When they are connected in series, the current through both bulbs is same. Hence 60 W bulb will be more brighter because P = I2R.
