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?
