Question

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

Answer 1

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 = (work)/(time) }`

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

`\implies \bf Power = \cancel (1000)/(10)`

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