ATT Comp Test (FC) Question and Answer
[2026] | UPDATED ACTUAL Exam | Final
Review
• What is a GFCI? -✓✓ Ground Fault Circuit Interrupter (automatically shut's off
electrical flow in the event of an overload)
• TS Transformers -✓✓ Open: T doesn't generate output V
Short: could be partial which would then change number of coils so Ep would change or
Es

• What are some factors affecting shock? -✓✓ Amount of current, path of current,
amount of body resistance, and length of time current flows in body
• What is not a primary factor in severity of an electric shock? -✓✓ The general health of
the victim.

burns
• Electrical burns are what? -✓✓ Electrical current flowing through tissue or bones
• Arc burns are what? -✓✓ Electrical current flowing through tissue or bones
• Thermal contact burns are what? -✓✓ When skin comes in contact with hot surfaces of
overheated electrical conductors
• Factors of electrical accidents -✓✓ Unsafe equipment, unsafe environment, and
unsafe work practices
, • What should you do first if someone has been shocked? -✓✓ Remove the victim from
the source.

• What do the following letters mean in a basic schematic diagram? C, D, Q, S, T, TP,
AVC -✓✓ C - Capacitor, D - Diode, Q - Transmitter, S - Switch, T-Transformer, TP -
Test Point, AVC - Automatic Volume Control
• voltage drop -✓✓ The difference in voltage across an electrical device that has current
flowing through it.
• Applied voltage -✓✓ Sum of all voltage drops in the circuit.
• Faults in series are: -✓✓ Open, Short, Changed value
• What are the four basic TS steps? -✓✓ A)Analyze circuit
B)Check Setup
C)Calculate/measure values
D)Check Results
• What fault provides no resistance to current flow? -✓✓ A short.
• What fault causes resistance to increase or decrease? -✓✓ A changed value.
