Hi All,
I am starting to build a bipolar power supply with dual volt meters. If I was only interested in using a single current meter and put it in the ground leg, wouldn't it read incorrectly "the sum of positive and negative currents" drawn from this supply? In other words, if I drew 1 amp from the V+ supply and 1 amp from the V- supply, wouldn't the meter read 0 amps?
If so, so would you use a single current meter to measure total current draw from a bipolar supply?
Regards,
