PN-Reverse Bias

What happens to the width of the depletion region when a PN junction diode is reverse biased?

• It increases

• It decreases

• It remains unchanged

• It becomes zero

In reverse bias, what is the direction of the applied electric field?

• Opposite to the built-in field

• Circular

• Same as the built-in field

• Zero

What happens to majority charge carriers in reverse bias?

• They cross the junction

• They move away from the junction

• They recombine at the junction

• They convert to minority carriers
  

What is the main source of reverse current in reverse bias?

• Majority carriers

• Minority carriers

• Electrons from external battery

• Holes injected by the cathode

Why is the reverse current very small in reverse bias?

• There is no electric field
  

• Majority carriers are blocked

• The battery is weak

• The diode is in forward bias
