Question

$\star$500W bulb glows brighter than 200W bulb . Give reason . (1marks question )$\star$
​

Answer 1

Answer:

The filament bulb (200W and 500W is only consumed by filament bulbs) works on the two stage energy transformation process to produce light. ... That's why 500W bulb glows brighter than 200W bulb.

Answer 2

Answer:

• The filament bulb (200W and 500W is only consumed by filament bulbs) works on the two stage energy transformation process to produce light. ... That's why 500W bulb glows brighter than 200W bulb.

Here, Power P=V

2 /RorR=V

2 /P

In parallel V will be same for both so R∝

P1 .

Thus, 100 W bulb has more resistance than 220 W bulb.

Since, heat produced H=(V 2 /R)t, so 220 W has more brightness than 100 W bulb.
