Question

explain the brightness of the bulbs in both the circuits​

Answer 1

In a parallel circuit, 100W bulb glows brighter due to high power dissipation instead of an 80W bulb. ... In series, both bulbs have the same current flowing through them. The bulb with the higher resistance will have a greater voltage drop across it and therefore have a higher power dissipation and brightness.
