An op-amp connected to a pair of resistors and one of these devices creates a gyrator.
The Trouton-Noble experiment found that a freely suspended one of these devices orients itself perpendicular to the motion of the Earth. An op-amp connected to a pair of resistors and one of these devices creates a gyrator. For a spherical type of this device, one quantity equals four pi epsilon-nought over the difference of the reciprocals of the inner and outer radii. The namesake property of these devices is altered with the addition of a dielectric, and is defined as charge over voltage and is measured in Farads. For 10 points, name these devices that store charge, usually in the form of two parallel plates.
