In an electronic device, the current supplied to the electrodes is related to different types of processes inside the device: current density, change in spontaneous polarization, and change in dielectric properties. Two expressions for the electrode current are derived: one is based on the time derivative of the Shockley-Ramo theorem, the other on the time derivative of the dielectric tensor. This result is illustrated for a switching liquid crystal device and a two-dimensional flux tube.
