Question

A machine puts out 100 watts of power for every 1000 watts put into it. The efficiency of the machine is

Answer 1

Answer:

10%

Explanation:

Machine out put power =100 watt

Machine input power=1000 watt

We have to find the efficiency of the machine.

We know that

Efficiency of machine=
`(O.p)/(I.p)`

Where O.p=Output power

I.p=Input power

By using the formula

Efficiency of machine=
`(100)/(1000)=0.1`

Efficiency of machine (in percent)
`0.1* 100=`10%

Hence, the efficiency of machine=10%
