⟩ What are the differences between voltage and current controlled devices?
In any (electronic) device controlling parameter is current it is called current controlled device. eg bilpolar transistor- output current is a function of base current.
In any (electronic) device controlling parameter is voltage it is called voltage controlled device. eg Field effect transistor- output current is a function of gate voltage.
It depends on the inherent physical mechanism which defines the primary (independent) controlling parameter.
