Hey everyone! glad to be a new member on this site.
Ok so I understand that by definition voltage implies two locations and therefore Voltage from one point doesn't make sense. Would it be possible to build a voltmeter that had two separate wireless probes. They would each measure a signal and then send it to the voltmeter to subtract the difference?
I realize that it may be impossible and not make any sense.
Is there such thing as a simulated ground that can be used as a reference for each probe and subtracted later on to give you just the difference between the two probe points? Would that even give you a correct voltage measurement?
I'm sorry, if this doesn't make sense I'll do my best to clarify if needed. Thanks a lot!
