If my power supply is drawing only 2.30ma from a 14VDC what is its efficiency?
If my power supply is drawing only 2.30ma from a 14VDC what is its efficiecy without any load?
How do you calculate the efficiency of this power supply?
If I am missing something please let me know.
"its efficiecy without any load" is sort of meaningless, if it is drawing any power at all, and is outputting nothing, it's efficiency is zero. You'll get a more useful value if you have a (known) load, then, as the previous answer said, the ratio of output to input will give you the efficiency.
