TRUE OR FALSE- When different diode models are connected in series in such a way that they are oriented similarly i.e. will allow a specific current flow, the voltage required to forward bias the series connection is the forward voltage of the diode with the higher knee voltage specification. - When different diode models are connected in parallel in such a way that they are oriented similarly i.e. will allow a specific current flow, the voltage required to forward bias the parallel connection is lower than the forward voltage of either of the diodes knee voltage specification since they are connected in parallel i.e. their equivalent resistance is lower as well.
