Hello everyone.
I am trying to measure the current from electirc circuit. There is a arduino power supply which I measured on resistor and value is 3.8V. Resistor is 180 ohms which means that I need to get current value of 0.021A but when I measured it with multimeter with range in miliAmps it displays 0.4mA and in micro 4.0 microAmps and with regular Amps it is 0.02 . I don't know what is the problem.
I have two inputs for my positive lead. One is for V, mA, microA and ohms, other is for 10A MAX. Options for measuring Amps are 200microA , 200miliA, 10A. When I plug the lead to 10A and i choose measurement 10A it gives good calculation, but when I plug the lead for mA,microA and choose the option to measure in mA and microA it proveds different results. For example lead in 10A and 10A measurement gives 0.02 which is correct but lead in mA with mA measurement gives 0.4
