Question

A lamp consumes 1000J of electrical energy in 10s. What is it's power???
​

Answer 1

Explanation:

शक्ति = कार्य/समय

P = W/t

= 1000/10

= 100 J/Second

= 100 Watt

Answer 2

$\huge\bf{\underline{\underline{\gray{GIVEN:-}}}}$

• $\bf{\red{Electrical\: energy\:consumed\:by\:lamp}}\:=\:1000J\:$

• $\bf{\red{Time\:taken}}\:=\:10s\:$

$\huge\bf{\underline{\underline{\gray{TO\:FIND:-}}}}$

• The power.

$\huge\bf{\underline{\underline{\gray{SOLUTION:-}}}}$

$\red\bigstar\:\:\bf\purple{Power\:=\:\dfrac{Work\:done}{Time}}$

$\bf\pink{Here,}$

$\bullet\:\:\bf{\red{Electrical\: energy\:consumed\:by\:lamp}}\:=\: Work\:done\:$

$;\implies\:\:\bf{Power\:=\:\dfrac{1000}{10}}$

$;\implies\:\:\bf\green{Power\:=\:100\: Watt}$
