Pneumatic actuator Some types of pneumatic actuators include: Pneumatic actuator A pneumatic control valve actuator converts energy (typically in the form of compressed air) into mechanical motion. The motion can be rotary or linear, depending on the type of actuator. A Pneumatic actuator mainly consists of a piston or a diaphragm which develops the motive power. It keeps the air in the upper portion of the cylinder, allowing air pressure to force the diaphragm or piston to move the valve stem or rotate the valve control element. Valves require little pressure to operate and usually double or "triple" the input force. The
Electric potential energy three charges is: The energy density, or energy per unit volume, formula_9, of the electrostatic field of a continuous charge distribution is: Some elements in a circuit can convert energy from one form to another. For example, a resistor converts electrical energy to heat. This is known as the Joule effect. A capacitor stores it in its electric field. The total electric potential energy stored in a capacitor is given by where "C" is the capacitance, "V" is the electric potential difference, and "Q" the charge stored in the capacitor. The total electrostatic potential energy may also be expressed in
