ASSOCIATE CET COMPREHENSIVE 2026 EXAM QUESTIONS
AND ANSWERS GRADED A+
✔✔A three input NAND has two low inputs and one high input. The output is: - ✔✔High

✔✔You are servicing a power supply and have disconnected power. It has several 250
uF capacitors connected in parallel. To avoid shock, these capacitors: - ✔✔Should be
discharged to chassis ground, through a suitable resistor.
✔✔A schematic used in electronic servicing: - ✔✔is much like a road map for following
signals

disabling AC input power, discharge an HV PS by: - ✔✔draining through a large value
resistor to chassis ground

transformer? - ✔✔The operating frequency

represent? - ✔✔2.9 ohms
✔✔An "audio signal" is often defined as: - ✔✔frequencies in the 20 Hz to 15,000 Hz
range
✔✔_____________ will cause a generator to produce DC voltage rather than AC. -
✔✔The communtator

apply power, you should: - ✔✔insert a low resistance high wattage (100 ohm, 10w)
resistor in series with the power input
✔✔A ripple counter: - ✔✔is two or more logical flip-flops connected sequentially with the
input pulses toggling the first
✔✔When a voltage is applied to a capacitor: - ✔✔current is maximum at first, then
reduces as the capacitor becomes charged
, ✔✔An electrolytic capacitor in series between the power transformer and the rectifiers
in a power supply: - ✔✔is part of a voltage doubler circuit

to 6.3 v
✔✔A triac is frequently used: - ✔✔to electronically turn equipment on and off
✔✔A techician must be knowledgeable about "ESD": - ✔✔because static discharge can
destroy many components
✔✔In a motor, the counter emf voltage induced in the armature ________ the source
current. - ✔✔causes a decrease in
✔✔One significant difference between a TV antenna and a CB antenna would be: -
✔✔TV is polarized horizontal while CB is veritcal
✔✔Switching power supplies: - ✔✔are sometimes called DC to DC converters
✔✔Which of these would you likely find in a DC motor speed control circuit? - ✔✔an op-
amp

the secondary, one on each end and one in the middle. This is a - ✔✔center tapped
secondary transformer
