Round 7: Tossup 4

A quantum mechanical effect decreases the strength of these devices when their constituent materials have a low density of states. AC coupling uses these devices as high-pass filters, blocking direct current. (-5[1])In [emphasize] series, the strength of these (-5[1])devices equals the reciprocal of a sum of reciprocals. Resistance (-5[1])times a characteristic quantity of these devices equals (10[1])the time constant. An inductor and one of these devices make an oscillating circuit. A quantity named for these devices, which equals charge over voltage, can be increased by inserting a dielectric between two parallel plates. For 10 points, what circuit elements that store energy in electric fields name a quantity measured in farads? ■END■ (10[3]0[1])
