When a hummingbird visits a flower, its wings rub against the flower and leaves, and this can result in a noticeable charge on the bird. There is an opposite charge in the earth. We can consider the hummingbird and the earth to be the two electrodes of a capacitor. The capacitance for one species has been estimated to be 1.1 pF. If the bird accumulates a charge of +300 pC, what is the potential difference between the hummingbird and the earth?

We've seen that bees develop a positive charge as they fly through the air. When a bee lands on a flower, charge is transferred, and an opposite charge is induced in the earth below the flower. The flower and the ground together make a capacitor; a typical value is 0.64 pF. If a flower is charged to 30 V relative to the ground, a bee can reliably detect the added charge and then avoids the flower in favor of flowers...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
