Pneumatic circuit following devices operate using compressed gases, but are not normally thought of as being pneumatic circuits: Pneumatic circuit A pneumatic circuit is an interconnected set of components that convert compressed gas (usually air) into mechanical work. In the normal sense of the term, the circuit must include a compressor or compressor-fed tank. The circuit comprises the following components: In general, based on the application, a pneumatic cylinder is usually a single acting cylinder, where there is a single port in the cylinder and where cylinder extension is done by compressed air and retraction by means of open coiled spring.

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
