In the experiment, this time as an experiment. Measuring the voltage in a circuit by using a Digital Multimeter (DMM) by this experiment is divided into 2 DC and AC voltage measurements together. DC styleThis experiment can be used by the meter, find a DC voltage by the meter circuit, DMM per bracket that we want to know exactly that voltage, or the theory of parallel access to devices. By value, the voltage measured from the meter DMM with positive or negative when we continue the meter into the Terminal? If we want a positive pressure, our meter red cable with the positive terminal black line meter into the negative, which is a positive value means that we provide the value that has the same flow direction flow cycle tee. 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. By measuring values may be not equal to the value of the error theory, tools, or crash out of the trials.Model ACBy this experiment can be used AC voltage meter, find it by the meter, the circuit, DMM, we continue out of curiosity or pressure that is parallel to the theoretical values into the circuit per the pressure measured from the meter DMM most value will be positive because the supply switch are in the form of a wave, sineusoud is exactly the cause must charge voltage from positive (positive V peak), 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.
