Question

100 watt bulb and 500 Watt bulb are connected in parallel to the mains
which bulb will glow brighter and why?​

Answer 1

Answer:

500 watt bulb will glow brighter

Explanation:

Because the bulb is taking more energy that's why

Hope this will help you

Answer 2

Answer:

500W

Explanation:

When connected in parallel,

R₅₀₀ = V²/P             R₁₀₀ = V²/P

       = x/500                  = x/100

R₅₀₀/R₁₀₀ = x/500 / x/100

x cancel

R₅₀₀/R₁₀₀ = 100/500

               = 1/5

∴5×R₅₀₀ = R₁₀₀

⇒R₅₀₀ < R₁₀₀

So, bulb of 100W will glow brighter.
