ATT Test 5 - Questions And Proper Answers

Transistors Right Ans - transfer resistance from low (EB) to high resistive
(CB) circuit

N-Type material Right Ans - made from free electronics
negative

P-Type material Right Ans - made with holes
positive

emitter Right Ans - heavily doped, produces current carriers

base Right Ans - very thin and lightly doped, allows carriers to pass from
emitter to collector

collector Right Ans - moderately doped, collects carriers, dissipates heat

NPN biasing Right Ans - DC V must be positive compared to emitter, EB
must be forward biased and CB reverse biased

Kirchoff's Law of Current Right Ans - Ie= Ib+Ic

PNP biasing Right Ans - base DC V must be negative compared to emittor,
base to emittor PN junction forward biased, collector to base PN junction
reverse biased

What effect does increasing base bias have on the collector? Right Ans -
collector will keep current at a constant level

Saturation Right Ans - point where Ic no longer increases even though base
bias voltage still increases, transistor will act as a short between collector and
emittor

What effect does decreasing base bias voltage have on the emitter? Right
Ans - stops current flow

cutoff Right Ans - collector to base PN junction reverse biased
