✍️ Sample CET Questions & Answers
1. What power level does 0 dBm represent?
0 dBm is defined as a power of 1 milliwatt; it is the 0 dB reference point on the dBm scale.
2. Which standard of practice is MOST important for ensuring quality in Follow-Up & Survival Analysis?
Evidence-based protocols provide a foundation of proven practices, but effective Certified Electronics Technician professionals must also adapt their approach based on specific circumstances and individual case needs within Follow-Up & Survival Analysis.
3. An inverting op-amp amplifier has a feedback resistor Rf = 10 kΩ and input resistor Rin = 2 kΩ. What is the closed-loop voltage gain?
Inverting amplifier gain = -Rf/Rin = -10k/2k = -5.
4. Which standard of practice is MOST important for ensuring quality in Staging & Prognostic Factors?
Evidence-based protocols provide a foundation of proven practices, but effective Certified Electronics Technician professionals must also adapt their approach based on specific circumstances and individual case needs within Staging & Prognostic Factors.
5. What causes thermal runaway in a BJT power amplifier?
As junction temperature rises, ICEO increases, boosting IC, which generates more heat — a destructive positive feedback cycle called thermal runaway.
6. What is the total resistance in a parallel circuit?
In a parallel circuit, the total resistance (R_total) is calculated differently than in a series circuit. The formula for total resistance in parallel is 1/R_total = 1/R1 + 1/R2 + ... + 1/Rn. This means you sum the reciprocals of individual resistances and then take the reciprocal of that sum to find the total resistance, reflecting that adding more paths for current flow actually decreases the overall resistance.
