Electric current can flow through a continuous path which can also  be described as a closed circuit. Conversely, any break or opening  in a circuit is called an open circuiâ¦t. Charges can only flow  through a closed circuit.
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.
