How to claculate the power consumption

Dear Arunakat1,

Thanks for clearing my doubt. I have one more query, i have gone thru. I/O specs and CPU specs e.g 314,315,etc, and the spec indicates power consumption in xxxmA. I don't quite understand why it is in mA instead of Watt or VA? Do you have any idea?

with regards,

how come?

Dear Arunakat1,

Thanks for your reply. The Spec is confusing, i think the spec should indicate current consumption instead of power consumption.Strickly speakingcurrent should goes with "Amphere" and power should goes with "Watt".

In this case if i want to obtain the power consumption in "watt", what should i do?

Thanks in advance!

Dear how come,

I think it’s easy if you want to go with watt you jest use this formula

P=VI cosf where P power in watts

V voltage in volts

I current in Amps

In DC cosf will be 0.

So if you know the current and voltage you can easily calculate the power in watts.

I hope this will help you.

Thanks. Wish you merry Christmas.
