A transistor in a Common Emitter transfers an internal resistance from a
low resistance in emitter base to? - CORRECT ANSWER ✔✔✔✔✔
High resistance in collector base.
Ie (Emitter current) = ? - CORRECT ANSWER ✔✔✔✔✔ Ib (base
current) + Ic (collector current)
When does cutoff occur in a Common Emitter? - CORRECT ANSWER
✔✔✔✔✔ When Emitter PN junction is reversed.
A Common Emitter has a gain of how much? - CORRECT ANSWER
✔✔✔✔✔ 10
How does a Common Emitter affect the phase of an input signal? -
CORRECT ANSWER ✔✔✔✔✔ It inverts the input 180 ° (flip)
A Common Collector has a gain of how much? - CORRECT ANSWER
✔✔✔✔✔ 1 (no phase inversion)
A Common Base has a gain of how much? - CORRECT ANSWER
✔✔✔✔✔ 10 (no phase inversion)
How do transistor amplifiers operate? - CORRECT ANSWER
✔✔✔✔✔ By an AC input signal changing base bias.
The component that develops bias for a transistor part is directly
connected to the_________. - CORRECT ANSWER ✔✔✔✔✔
Corresponding transistor part.
In a Common Emitter, if base voltage (base bias) increases, emitter
current does what? - CORRECT ANSWER ✔✔✔✔✔ Increases.
A small input controls a__________. - CORRECT ANSWER ✔✔✔✔✔
Large output
, What is the most common type of Multi-stage Amplifier? - CORRECT
ANSWER ✔✔✔✔✔ RC (Resistive-capacitive)
What is the purpose of Cascade amplifiers? - CORRECT ANSWER
✔✔✔✔✔ To increase Av (Voltage Gain)
How is AvT (Total voltage gain) calculated in a Cascade Amplifier? -
CORRECT ANSWER ✔✔✔✔✔ The product of individual stage
gains (Q1xQ2xQ3x...=AvT)
What is the typical gain for a three stage cascade amplifier (assumed
value)? - CORRECT ANSWER ✔✔✔✔✔ 1,000
What is Cascading? - CORRECT ANSWER ✔✔✔✔✔ The
connecting of multiple amplifiers in series.
What is step 1 of the Multi-Stage Amplifier Troubleshooting process? -
CORRECT ANSWER ✔✔✔✔✔ Check output, compare measured
Av to Calculated Av.
What is step 2 of the Multi-Stage Amplifier Troubleshooting process? -
CORRECT ANSWER ✔✔✔✔✔ Check individual stage gains.
What is step 3 of the Multi-Stage Amplifier Troubleshooting process? -
CORRECT ANSWER ✔✔✔✔✔ Check components of isolated
stage, start with transistor.
What is step 4 of the Multi-Stage Amplifier Troubleshooting process? -
CORRECT ANSWER ✔✔✔✔✔ If the transistor is not at fault, turn
off power and take resistance measurements. Replace Faulty
component.
Is a value of 1100 acceptable in a three stage Cascade Amplifier
(assumed value)? - CORRECT ANSWER ✔✔✔✔✔ Yes. There is an
assumed error margin of ±10%. 1100 falls within the assumed value of
1,000's margin.
What is the purpose of a Push-Pull Amplifier? - CORRECT ANSWER
✔✔✔✔✔ To amplify power. PPP: push-pull power.
