Round 3: 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. In [emphasize] series, the strength of these devices equals the reciprocal (-5[1])of a sum of reciprocals. (10[1]-5[1])Resistance times (-5[1])a characteristic quantity of these devices equals the time constant. An inductor and one of (10[1])these devices make an (10[1])oscillating circuit. A quantity named for these devices, (10[1])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 (10[1])fields name a quantity (-5[1])measured in farads? (10[1])■END■ (0[2])
