Round 4: 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 (10[1])[emphasize] series, the strength of these devices equals the reciprocal of a sum of reciprocals. (-5[1])Resistance times a characteristic (-5[1])quantity (10[1])of these devices equals the time constant. (10[1]-5[1])An (10[1])inductor and one (10[1])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. (10[1])For 10 points, what circuit elements (10[1])that store energy in electric fields (10[1])name a quantity measured in farads? ■END■
