Abstract
A circuit for supplying direct current to a line (a, b) from a battery via two supply resistors (RA, RB). Part of the current supplied by the battery flows in a secondary path including a resistor (R4) and a transistor (16), and is maintained at a constant value. A symmetrical and differential resistance bridge connected between the supply resistors and the line detects the transverse alternating current flowing into the battery, and means (15) are provided to cause the transistor to generate a negative-feedback alternating current whose value is adjusted to cancel said transverse alternating current.
