While I was working in an AC current lab, I used a very simple circuit. 1 resistor and a wave generator. The voltage was about 3V (RMS) and the resistance 1.173 kohm. According to Ohm's law i.e. V=IR I should have a current flow around 2.5 mA. But the multimeter showed me a quite different value, that is .2 mA. What is the problem, is there anything I missed?
Here are a couple of possible reasons the reading could be wrong:
To check the above possibilities, an oscilloscope would come in handy:
