3 0

Explanation:

The efficiency of a system is the ratio of the output of system to the input of that system.

For a light bulb;

  Efficiency =  Power output / Power input

  Efficiency is used in rating a bulb.

It is impossible to find a system that has 100% efficiency because the total power input is not converted to the output delivered.
