hi sounds like quite a beginner question but I need to find out how much ma a device is using
as I'm having some trouble getting some components to work together through a power supply i have looked on the multimeter but can't seem to locate what i need and where on the component i need to add this to
the component in question is a peltier that i believe is 12v but due to it being sealed in a part i can not see
any advice would be great
many thanks
shane
Another way is by measuring resistance, and doing some math.
Someone corect me if i am wrong, it has been a while sence i took my law exam, but.
If you put your meter into the ohm setting, and with no power on, and the device unhooked from other circuts,
take the two meter probes and get a reading of the ohms that it has.
than using the middle formula, Take your voltage, (12) I am guessing and divide that into the Resistance (50) "Just using 50 as an example, i have no idea what it really will be".
And you should have amps, ( 12/50=.24 amps.....) Just using as an example!!!
TADA!
hope it helps.
