18.5: Capacitors
Capacitors are common electronic devices that are used to store electric charge for a variety of applications. A capacitor is usually constructed with two conducting plates (called "terminals" or "electrodes") separated by either air or an insulating material. Figure (PageIndex{1}): Two examples of capacitors.
Cryogenic Cooling
The drilling thrust of cryogenic cooling is larger than that of dry conditions due to the high deformation resistance of CFRP at low temperatures. Joshi et al. [107] found that delamination increased with feed rate under dry and cryogenic cooling conditions. The delamination coefficient first decreases and then increases with the rise in ...
