Dc Circuits. A circuit is a closed loop through which electrons can flow. A direct current (DC) circuit is a type of circuit with direct current (as opposed to alternating current) flowing through it. That is, in a DC circuit, the current flows in one direction.
In electrical signalling an analog current loop is used where a device must be monitored or controlled remotely over a pair of conductors.asic DC circuit theory shows that the current is the same all along the line. It was common to see 4â20 mA circuits that had loop lengths in miles or circuits working over telephone cable pairs that were longer than ten thousand feet end-to-end. There are still legacy systems in place using this technology.
