SECTION 1: DIODE FUNDAMENTALS & OPERATING
MODES (Questions 1–10)
1. A diode operates in two primary modes. What are they?
A) Saturation and cutoff
B) On (conducting) and Off (non-conducting)
C) Forward and reverse saturation
D) Active and passive
Correct Answer: B
Rationale: A diode operates in two modes: on and off. When forward-biased
(voltage across the diode is positive), current flows from anode to cathode
and the diode is on. When reverse-biased, the diode is off and current is
approximately zero .

2. When a diode is forward-biased, current flows from:
A) Cathode to anode
B) Anode to cathode
C) Base to emitter
D) Drain to source
Correct Answer: B
Rationale: When a diode is forward-biased, current flows from anode to
cathode. This is the conventional current direction, opposite to the direction
of electron flow .
