01.Hydraulic Actuator vs Electro Mechanical Actuator

An Actuator is a component that moves / controls a system by converting energy into mechanical motion. For the use of Aircraft applications, the main sources of energy are hydraulic pressure (Hydraulic Actuator) and an electric current (Electro Mechanical Actuator).
