Question

$\boxed\bf{Question}$

Three bulbs of 40 W 60 W and 100 W are arranged in series across the mains, Across which the potential difference is highest? Which bulb has lowest potential difference? ​

Answer 1

We Know,

Formula of Power = V × I

we know that in Series the Current across all the Components remain Same ' ɪ '

Potential Difference across,

$40w \: bulb \: = \: \frac{40 \: w}{i}$

Potential Difference across,

$60w \: bulb \: = \frac{60}{i}$

Potential Difference across,

$100w \: bulb \: = \frac{100}{i}$

Clearly ,

we can say that potential difference across 100 w bulb is Maximum & minimum across 40 w bulb
