A technician is testing a rectifier bridge using a DMM in the diode test mode. She measures 0.7V when each diode is forward biased and the DMM indicates OL when each diode is reverse biased. What do these test results indicate?
A) The results indicate the rectifier bridge is defective because of the OL indication when each diode is reverse biased.
B) The results indicate that this is definitely a positive rectifier bridge.
C) The results indicate she is not testing the rectifier bridge correctly.
D) The results indicate that none of the diodes in the rectifier bridge are shorted or open.

The results indicate that each diode is functioning correctly, as a forward-biased diode should show a voltage drop (typically around 0.7V for silicon diodes) and an open circuit (OL) when reverse-biased, indicating no shorts or opens.
