Two identical 60 W bulbs are connected in parallel first and then in series to the 220 V mains.
What is the power dissipated by each bulb and the total power dissipated by the bulbs in the case of a parallel connection?
What is the power dissipated by each bulb and the total power dissipated by the bulbs in the case of a series connection?
Assume that the resistance of the bulbs does not change.
