Hi all, I have a spot welder design for which I bend to measure the ac voltage of 2-3v. Since the voltage is ac should it be rectified and filtered before sending it via the ADC ? Amp is several 1000's. To measure the amps put into spot by the electrode a formula came across is menationed on anothe…
