Design And Construction Of Ac Voltmeter Using Computer Interface

ABSTRACT Voltage is a fundamental quantity that is important in every phase of electrical engineering from power system to voltage inside VLSI chips. Of The need to measure the output voltage of a supply is very important meanwhile, The voltmeter is an instrument for measuring voltage, it could be digital or Direct voltage, meanwhile, the rectification process of the alternating voltage using diode, make, it more possible for ac voltages to be measured. However, the need for modernization makes it necessary to use computer to view the output of the voltage in either graphical or numerical for…
