- The variable capacitance of an old radio tuner consists of four plates connected together placed alternately between four other plates, also connected together (Fig. 19–92). Each plate is separated from its neigh- bor by 1.6 mm of air. One set of plates can move so that the area of overlap of each plate varies from 2.0 cm² to 9.0 cm?. (a) Are these seven capacitors connected in series or in parallel? (b) Determine the range of capaci- tance values. FIGURE 19-92 Problem 95.
