What is a shear pin used for? CORRECT ANSWERS A mechanical fuse designed to
break under specific torque
Which has the highest viscosity? CORRECT ANSWERS Honey (Vicosity is how thick
something is)
When a device or wire is shorted, what is the indication in the circuit? CORRECT
ANSWERS High current and low resistance (Ohm's Law V = IR)
What is used to protect electronic equipment from electrostatic discharge? CORRECT
ANSWERS Wearing a grounded wrist strap
A logic gate has multiple inputs and one output. When any of the inputs is high, the
output is high. What type of gate is it? CORRECT ANSWERS OR Gate
What logic function does the truth table in Figure D represent?
A|Y
0|1
1|0 CORRECT ANSWERS Inverter
What is the time required for a signal to move through a logic circuit called? CORRECT
ANSWERS Propagation delay
What maximum size fuse should be used in a circuit with 4200W of power and
120VAC? CORRECT ANSWERS 30 Amps. A fuse is a safety device; maximum safety
listed for 35A is 30A
A class C fire extinguisher uses which component to extinguish a fire? CORRECT
ANSWERS CO2
Before removing a blown fuse, what should be done? CORRECT ANSWERS Remove
electricity
Two Technicians and One mechanic are assigned to work on a circuit that must be de-
energized; how many Iockouts are required? CORRECT ANSWERS 3 (one for each
person with one key each)
A fuse gets hot while in a circuit. What can be the underlying cause? CORRECT
ANSWERS Fuse clips have poor connection or improper tension
, Grounding conduit prevents the conduit from being: CORRECT ANSWERS Charged to
a higher potential than ground
Which component might be damaged by static electricity? CORRECT ANSWERS
Transistor
If the p-p voltage of a sine wave is 200V, what is the RMS value? CORRECT
ANSWERS 70.7 V
In a purely capacitive circuit, which leads by 90°: CORRECT ANSWERS Current (ELI
the ICE man)
What type of file is used to file a round hole? CORRECT ANSWERS Rattail
Which tool is used to remove a rivet head? CORRECT ANSWERS Chisel
Which tool should be used to remove a gear from a shaft? CORRECT ANSWERS Gear
puller
What are diagonal pliers used for? CORRECT ANSWERS Cutting wires a.k.a. wire
cutters
When measuring the distance between the flat edges of a spark plug, what tool is used?
CORRECT ANSWERS Feeler gauge
What does a Vernier caliper measure? CORRECT ANSWERS Inside diameter
When checking a circuit that has a maximum voltage of 24V, what range should the
meter be set to initially when checking Voltage in the circuit? CORRECT ANSWERS
25V
You need to check a fuse in a circuit where it is not advantageous to tum off the power.
What should the meter be set to and what will the reading be if the fuse is good?
CORRECT ANSWERS Max Voltage for the circuit, OV reading.
When checking across the leads of a capacitor with an analog meter you note that the
needle jumps to zero and then slowly moves to infinite resistance. What have you just
determined? CORRECT ANSWERS The cap is probably good
When checking across the leads of a capacitor with an analog meter you note that the
needle jumps to and stays there. What have you just determined? CORRECT
ANSWERS The capacitor is shorted
Which is typically used for repairing layered printed circuit boards? CORRECT
ANSWERS Variable wattage soldering station
