Question

in reverse bias of a diode
anode is negative with respect to cathode
at very high reverse voltage, breakdown may occur
a small leakage current (reverse saturation current) flows
diode conducts current like a normal resistor
what happens when a diode is forward biased?
it allows current to flow
it acts as an open circuit
it blocks current completely
it stores charge

Explanation:

In reverse - bias of a diode, the anode is negative with respect to the cathode, a small leakage current (reverse - saturation current) flows, and at very high reverse voltage, breakdown may occur. A diode does not conduct current like a normal resistor in reverse - bias. In forward - bias, a diode allows current to flow.

Answer:

In Reverse Bias of a diode:

• Anode is negative with respect to cathode: True
• At very high reverse voltage, breakdown may occur: True
• A small leakage current (Reverse saturation current) flows: True
• Diode conducts current like a normal resistor: False

What happens when a diode is forward biased?

• It allows current to flow: True
• It acts as an open circuit: False
• It blocks current completely: False
• It stores charge: False
