Digital Electronics – ATT Test 8 – Logic Gates, IC
Classification, Flip-Flops, and Timer Circuits (Q&A
Format)
What happens to the conduction of Q2 if the output voltage increases? decreases
In any power supply, which block may contain an over current protection circuit?
regulator
Which type of relay uses a bimetallic strip as the common terminal? Thermal Time Delay
Relay
Relays can have ? One or more poles
What corrective action should be taken for a failed sealed relay? Replace entire relay
The first step in checking a relay is to? Check inputs
Normally when the relay is energized, -ISU is present on the output contact, this time, the relay
is energized, but 0 volts is present, possible fault? Input 2 voltage is incorrect
The dc motor operates using ? Direct current, dc voltage, electrical energy produces

field coil in a series field motor
When a schematic diagram shows a field coil, you instantly know the motor is ?
Electromagnet
How many types of compound motors are there? 2
In a delta connected alternator ? The line voltage = the phase voltage
What generates rotor current in an ac conduction motor? Stator Magnetic field
Which type of ac motor is used for large horsepower or special applications?
synchronous
In an ac generator, the output voltage across the load in the external circuit reverses polarity
with ? Every 180 degrees
