hello ,
DC (I guess AC too) power supplies have 3 terminals: plus, ground, minus.
If I set the voltage to 30 Volts, and plug one cable in the + terminal and the other in the - terminal, is the voltage across the wires 30 volts or 60 volts? When do we use the ground or the negative?
I tried with one powersupply and it gave me 60...
thanks!
