The two electric bulbs of 60W and 100W are given. Which one will be brighter when they are connected (i) In Series and (ii) In Parallel? And Why?
1. The resistance of a 60W bulb is much more than that of 100W bulb. When they are connected in series. 40W bulb will be more brighter (where P=I^2R).
2. When the two bulbs are connected in parallel, the 100W bulb will be more brighter (where P=V^2/R).
