Question

a lamp consumes 1000 J of electrical energy in 10s what is the power ?​

Answer 1

Answer:

the power of the lamp is 100 Watts

step by step explaining:

work done = energy consumed by the lamp = 100J

time = 10 seconds

power = 100 / 10 = 100J - 1 = 100w

Answer 2

$\bf \underline{ \underline{Given}}$

• Work,W = 1000 J

• Time taken,t = 10 s

$\bf \underline{ \underline{To \: find \: out}}$

Calculate the power of lamp.

$\bf \underline{ \underline{Solution}}$

Formula of power is work done divide by time taken.

$\boxed{ \bf \: Power = \frac{work}{time} }$

$\blue \bigstar \bf \: Putting \: the \: given \: values$

$\implies \bf Power = \cancel \dfrac{1000}{10}$

$\implies \bf \: Power = 100 \: watt$
