Round 2: 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, (10[1])the strength of these devices equals the reciprocal (10[1])of a sum (10[1])of reciprocals. (10[4]-5[1])Resistance times a characteristic quantity of these devices equals the time constant. An inductor and one of these devices make an oscillating (10[1])circuit. A quantity named for (10[1])these devices, which equals charge over voltage, can be increased by inserting a dielectric (10[1])between two parallel plates. (10[1])For 10 points, what circuit elements that store energy in electric fields name a quantity measured in farads? (10[1])■END■
