Why is the ability of a diode to allow current in only one direction significant in electronic circuits?

Multiple Choice

Which terminal of a diode is usually marked by a line?

• Anode

• Cathode

• Emitter

• Base

Multiple Choice

Which part of a diode allows current to flow through it, and in which direction does the current flow?

• From anode to cathode

• From cathode to anode

• Both directions

• Neither direction

Open Ended

Explain how a diode in a computer mouse helps protect the device when the battery is inserted incorrectly.

Multiple Choice

Which of the following statements about diode biasing is correct?

• A forward biased diode allows current to pass.

• A reverse biased diode allows current to pass.

• A forward biased diode prevents current from flowing.

• A reverse biased diode allows maximum current to pass.

Multiple Choice

What happens to a diode if the forward current exceeds the maximum value specified by the manufacturer?

• The diode may be damaged.

• The diode will conduct more efficiently.

• The diode will block all current.

• The diode will reverse its polarity.

Open Ended

Explain how the current through a diode changes as the reverse bias voltage approaches and exceeds the reverse breakdown voltage (V_Rmax).

Multiple Choice

What is the significance of the reverse breakdown voltage (V_Rmax) in a diode's operation, and what happens when the reverse bias voltage exceeds this value?

• The diode continues to operate normally as a one-way valve.

• The current decreases rapidly in the reverse direction.

• The diode may be damaged and will no longer operate as a one-way valve.

• The forward voltage drop increases.

Multiple Choice

• B

• C

• D

Multiple Choice

Which letter on the diode characteristic represents the reverse current (I_R)?

• A

• B

• C

• D
