In a circuits lab, at first I connected a DC power supply to the DMM in parallel, and measured the voltage.
Then, I added a resistor in parallel with those two, and the voltage drops slightly by 0.005.
Could you give an explanation as to why this is happening? It\'s a 10 ohm resistor by the way. Thanks!

Solution
A dvm has analog to digital converter..,so basically its analog measurement then its digital counter conversion.,how does a measurement actually done? Though it is seen that we are measuring voltage we actually sense current ,by parallel addition of resistor the current sensed will be less ,so less the voltage because of which u got drop in voltage
