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
You need a multimeter that measures current. Disconnect the power supply line going to the Peltier Cooler and insert the multimeter in series with the Peltier cooler. Some multimeters do not measure current, so your may not be able to. Having said that, it is a fairly common measurement and most multimeters do have the ability to measure current.
Have a look at this multimeter:

You can see there are four ports on the bottom. One is ground or common, one is for voltage or resistance measurements, the other two are for different scales of current measurement.
