Two (non-physics) students, A and B living in neighboring hostel rooms, decided by economies by connecting their bulbs in series. They agreed that each would install a 100 W bulb in their own rooms and that they would pay equal shares of the electricity bill. However, both decided to try to get better lighting at the other's expense, A installed a 200 W bulb and B installed a 50 W bulb. Which student is more likely to fail the end-of--term examinations ?

Answer

`P_(A)=8W&P_(B)=32 W`, A is more likely to fail his examinations
