including a full wave rectifier in an AC circuit will yield a ----- current. A)intermittent direct. B)intermittent alternating. C)continuous direct. D)continuous alternating.

Full wave rectifier will reverse the negative waves, making the output voltage waveform like continuous hills.

See the graph Vout. As for your answers, none of them are really good, C is the best one, as long as one does not mean by "continuous" constant. It takes a filter to make the DC constant.

the answer is c
