A variable capacitor used for tuning radios is shown in Figure 8.2.5 . One set of plates is fixed to the frame while an intersecting set of plates is affixed to a shaft. Rotating the shaft changes the amount of plate area that overlaps, and thus changes the capacitance. Figure 8.2.5 : A variable capacitor. For large capacitors, the capacitance value and voltage rating are usually printed
