Question

Umesh has two bulbs having
resistances of 15 W and 30 W. He
wants to connect them in a circuit,
but if he connects them one at a time
the filament gets burnt. Answer the
following

Answer 1

Answer:

When Umesh connects the bulbs one at a time, the filaments of the bulbs get burnt. This means the heat energy generated in the filament is beyond what it can tolerate. ... If bulbs are connected in series, the effective resistance of the circuit increases and hence current through the bulbs decreases.
