Question

lens wonder trade 220 V ,50w and other rated 220v 100w are connected in series with main of voltage 220v which lamp full consume more power and why​

Answer 1

Answer:

Two lamps one rated 220v,50w and the other rated 220V,100W

are connected in series with mains of 220V.

From equation, P=V²/R, ⇒R=V²/P

we can say the resistance of bulb is inversely proportional to power consumed.

So bulb with 50W has more resistance.

If two bulbs are connected in series connection then same current will flow through each lamp.

We know that

H=I²RT

Since the resistance of Bulb with 50w is more so it consumes more electrical energy and will glow more and bright.
