Answer:
10%
Step-by-step 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=[tex]\frac{O.p}{I.p}[/tex]
Where O.p=Output power
I.p=Input power
By using the formula
Efficiency of machine=[tex]\frac{100}{1000}=0.1[/tex]
Efficiency of machine (in percent)[tex]0.1\times 100=[/tex]10%
Hence, the efficiency of machine=10%
