aiva said:It is known, current sources may be with grounded or not grounded load. Does anybody know what kind of circuit is better :?:
Thanks In Advance.
I can't view your attachment.aiva said:OK, I'll try (excuse me for my English)
As I can see from Tietze&Schenk there are two common principles for current source building.
Grounded load (Fig. 1) and not grounded load (fig. 2).
I have to make a proved choice from one of these shems for supplying the temperature sensor on long line. But I can't see any criterion for choosing. Is it here or these diagrams are equivalent in meaning of current accuracy?
