Idling current
Idling current refers to the small amount of current trickling through a circuit (or more commonly through transistors) such as an amplifier when the system is on, but doing no useful work. Analog electronic circuits sometimes need to be designed while keeping the idling currents in mind, as these currents may be used to run other components in the circuit, or, more commonly, will result in undesired noise in the output.
