A single phase – half wave controlled rectifier with freewheeling diode is supplying a load consisting series connected a resistor and an inductance from a 70.7V (RMS), 50HZ sinusoidal AC source. The firing delay of the thyristor is 90° and the load values are R=10Q, L=0.1 H. Define the load current expression and draw the load current by calculating for first two periods. And calculate the average values of the load voltage and current.

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.
