Q: What is the main function of transistors?
ANSWER ✔✔ Transistors transfer resistance from low (EB) to high resistive (CB) circuit.
Q: What is N-Type material made from?
ANSWER ✔✔ Free electrons; it is negative.
Q: What is P-Type material made from?
ANSWER ✔✔ Holes; it is positive.
Q: What is the role of the emitter in a transistor?
ANSWER ✔✔ It is heavily doped and produces current carriers.
Q: What is the role of the base in a transistor?
ANSWER ✔✔ Very thin and lightly doped, it allows carriers to pass from emitter to collector.
Q: What is the function of the collector in a transistor?
ANSWER ✔✔ It is moderately doped, collects carriers, and dissipates heat.
Q: How is an NPN transistor biased?
ANSWER ✔✔ DC voltage must be positive compared to the emitter; the emitter-base junction
is forward biased, and the collector-base junction is reverse biased.
