If the work input of a machine is 30 joules,what would be it's efficiency when the output is 25 joules?

Sagot :

The efficiency of the machine is 83.3% when the output is 25 joules.

What is efficiency?

This can be defined as the ratio of the work output to the work input of a machine, expressed in percentage.

To calculate the efficiency of the machine we use the formula below.

Formula:

• E (%) = (Wo/Wi)100........... {Eq1}

Where:

• E (%) = Efficiency of the machine

• Wo = Work output

• Wi = Work input.

From the question,

Given:

Wo = 25 Joules

Wi = 30 Joules

Substitute these values into equation 1

We have,

• E (%) = (25/30)100

• E (%) = 83.3%

Hence, the efficiency of the machine is 83.3%.
