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
