Question

A lamp consumes 1000J electrical energy in 10s. what is its power?

Answer 1

Given:

Electrical energy = 1000J

Time consumed = 10sec

To find:

Power = ?

Solution:

Power= Energy/Time

P = E/t

Power = 1000/10

Power = 100 watts = 0.1 kilowatt

Answer 2

$\textbf{\underline{\underline{According\:to\:the\:Question}}}$    

$\tt{\implies Power =\dfrac{Work\:Done}{Time}}$

By the Information of Question

Electrical Energy = Work done = 1000 Joule

Time = 10 Seconds

${\implies Power =\dfrac{1000\:J}{10\:second}}$

Power = 100 Watt
