no, I'm trying to figure the efficiency of the circuit.
according to the service sticker ( laptop power cube ) the input is 120v 1.6A
and the output is 19v 3.16A,
120 x 1.6 is 180W rms
and 19v x 3.16A is 60.04W rms right?
so there's about 120W of power being wasted unless I'm not doing this...
OK, so if I'm inputting 120V ac @ 1.5A equals 180W
and my output is 19V dc @ 3.16A equals 60.04W
simple subtraction says 116W is left. that can't be right can it?
am i doing this wrong or am i actually losing 116W of power?
ok, so basically it depends on how expensive the calculator is, a cheap calc like you get from someone in a gift basket is just a couple of logic gates but a scientific calc actually has the basics of a computer right?
thanks for the reply btw:
hello, I'm new here so help me out please.
question: what does a pocket calculator use to convert binary into decimal data?
I've always been curious about this.
a calculator is nothing but a simple computer right? therefore it's core component consists of a microprocessor which instructs and...
