es- Umesh has two bulbs having resistances of15 Ί and 30 Ί. He wants to connect them in acircuit, but if he connects them one at a timethe filament gets burnt. Answer the following.i. Which method should he use to connect thebulbs? |

Answer» Two bulbs joined in parallel would have importantly reduced resistance even if the current has to be divided upon them , consider each one of 15 ohms and a voltage of 30 volts if they were connected in series , total resistance would be 30 ohms and so intensity will be 1 amp and in parallel it would be 7.5 ohms. so which method should be used |
