CONSTANT CURRENT CIRCUITS Abstract of the Disclosure A constant current circuit includes a first constant current source including a transistor and a resistor, and a second source also including a resistor and a transistor which is controlled via a differential amplifier to produce a second constant current equal to the first. The differential amplifer has inputs connected to tapping points of similar potential dividers coupled between the current sources. The circuit is particularly applicable for supplying d.c. sealing current via center-tapped transformer windings to the two balanced wire pairs of a four-wire transmission line. -i-
