     Reverse bias of a diode is a condition that essentially  current through the diode.  A) amplifies  B) increases  C) allows  D) prevents 
  
  Solution
Answer:
Reverse bias of a diode is a condition that essentially ___________ current through the diode.
Option D
Prevents
Reverse bias of a diode is a condition that essentially PREVENTS current through the diode.
At reverse biased diode used in the circuit behaves as open circuit. As the diode produces infinite resistance. So current prevents for certain point i.e Breakdown voltage.
