Recent research has highlighted the potential of ferroelectrics to cause a negative value for this variable to improve the performance of amplifiers. One form of this variable interacts with the ideal inductance at the self-resonant frequency to cause the inductor to become an open circuit. This variable for an inverting voltage amplifier is increased in the typical example of the (*) Miller effect. A matrix consisting of this variable can be calculated from the reciprocal of the coefficients of potential in an elastance matrix. The “self” form of this variable for a conductor can be calculated from the charge divided by the potential. For 10 points, name this variable which quantifies a namesake object’s ability to store (10[1])charge and has the SI unit (10[1])of farads. ■END■
