What am i doing wrong here?
ElectricPower:
This may be a very stupid question from an amateur, but how do you measure how many amps the strip in the picture draws with a multimeter?
I set the multimeter wheel on mA and connect the red contact to rhe mA port on the meter. When i do this the led strip light turns of and turns on when i remove the probes.
I just want to measure how many amps (mA) this led strip uses.
ArthurDent:
If you have the meter set to ma and connect it between plus and minus for the LEDs, you are shorting the supply output. If you put the meter in series with the positive lead to the LEDs, you will measure current.

Do you mean like that?

Hi
You measure Voltage ACROSS 'things' and you measure current IN-LINE with 'things' unless the expectant current is reasonably high or you are measuring ac then you could use a clamp meter.
Estimate the magnitude of the current you are measuring to see if your meter is capable and not to blow it's fuse. Always set your meter on the highest range (usually 10 or 20A) and switch down the ranges as necessary.
With power off remember, break the circuit. Assuming you have connected your probes correctly (if required), connect the positive (usually red) meter lead to the most positive point of the broken circuit, and the negative (usually black) lead to the other part of the broken circuit.
