In this experiment the experiments measuring the voltage in a circuit by using a Digital Multimeter (DMM) by this experiment is divided into 2 DC and AC voltage measurement DC style together.This experiment can be used by the meter, find a DC voltage by turning the potentiometer circuit, DMM per bracket that we want to know what the pressure theoretical or direct that is parallel to the entrance fee per cycle from the pressure gauge from meter DMM with positive or negative when we angled into the Terminal approval meter if we want positive voltage to us per meter red cable to the positive terminal black line meter into the negative, which is a positive value means that we provide the value with the same flow direction flow เดีนส t circuit. The pressure from the meter each dropout which we have once counted and will have a value equal to or close to the pressure on labor supply. Comanche measuring values may be not equal to the value of the error theory, tools, or crash out of the trials.Model AC
