Question
“Fractional” examples of these devices correspond to a fractional order between -1 and 0 in the constant phase element model. For 10 points each:
[10m] Name these devices whose “pseudo” form operate via charge transfer at their electrodes, such as by undergoing a redox reaction. Another type of these devices operates via the formation of a Helmholtz double layer.
ANSWER: capacitors [or fractional capacitors; or supercapacitors; or pseudocapacitors]
[10e] Non-supercapacitors often have their capacitance increased by inserting one of these polarizable materials between their electrodes.
ANSWER: dielectrics
[10h] This quantity for a dielectric is only non-zero due to the capacitor’s fringing field, making it hard to compute. Instead, most textbooks derive the equation for this quantity via an energy method in which the dielectric is moved infinitesimally.
ANSWER: the force on the dielectric [or the force on the capacitor; prompt on F] (see Eric Dietz, “Force on a dielectric slab: Fringing field approach” and Paul Gluck, ‘‘Force on the dielectric in a parallel plate capacitor’’ for some extremely cool physics involving directly calculating the force from the fringing field)
