In electric or capacitive coupling (electrostatic induction) the transmitter and receiver coupling devices are electrodes such as metal plates, and the transmitter and receiver electrodes form a capacitor, with the intervening space as the dielectric.
In electric or capacitive coupling (electrostatic induction), the dual of inductive coupling, power is transmitted by electric fields. The transmitter and receiver coupling devices are electrodes such as metal plates, and the transmitter and receiver electrodes form a capacitor, with the intervening space as the dielectric.
